Attention to Detail Test Practice Course: Invoices, orders and schedules

1. Question 1 of 18

   An invoice line shows 12 boxes at $4.75 each, with a line total of $47.50. What should the line total be?

   • A$16.75
   • B$570.00
   • C$47.50
   • D$57.00
   Show answer

   Answer: D. $57.00

   12 × $4.75 = $57.00. The invoice total of $47.50 is the price of only 10 boxes.

2. Question 2 of 18

   Check each line of this invoice (quantity × unit price). Which line has an error?

   Item	Qty	Unit price ($)	Line total ($)
   Paper towel (case)	24	3.15	75.60
   Floor cleaner (4 L)	6	18.40	110.40
   Garbage bags (box)	10	7.25	75.20
   Mop heads	3	42.00	126.00

   • AMop heads
   • BPaper towel (case)
   • CGarbage bags (box)
   • DFloor cleaner (4 L)
   Show answer

   Answer: C. Garbage bags (box)

   10 × $7.25 = $72.50, but the line shows $75.20 (the 2 and the 5 are swapped). The other lines are correct.

3. Question 3 of 18

   The line totals on this invoice are correct. What should the subtotal be?

   Item	Qty	Unit price ($)	Line total ($)
   Toner cartridge	2	89.00	178.00
   Copy paper (case)	5	46.50	232.50
   Binder clips (box)	4	6.25	25.00
   		Subtotal	453.50

   • A$453.50
   • B$257.50
   • C$435.50
   • D$410.50
   Show answer

   Answer: C. $435.50

   $178.00 + $232.50 + $25.00 = $435.50. The invoice shows $453.50, with the 3 and the 5 swapped.

4. Question 4 of 18

   An invoice shows a subtotal of $360.00 and tax at 5%. The tax line says $1.80. What should the tax be?

   • A$18.00
   • B$378.00
   • C$180.00
   • D$1.80
   Show answer

   Answer: A. $18.00

   5% of $360.00 = 0.05 × 360 = $18.00. $1.80 is ten times too small, a decimal-point slip. $378.00 is the total including tax.

5. Question 5 of 18

   Compare the purchase order with the supplier's invoice. Which item was billed in a larger quantity than was ordered?

   Item	Purchase order qty	Invoice qty
   Safety boots, size 9	10	10
   Safety boots, size 10	12	12
   Work gloves (pair)	50	60
   Rain jackets	8	8

   • ASafety boots, size 10
   • BRain jackets
   • CWork gloves (pair)
   • DSafety boots, size 9
   Show answer

   Answer: C. Work gloves (pair)

   The order was for 50 pairs of gloves, but the invoice bills 60. Always match each invoice line with the purchase order before approving payment.

6. Question 6 of 18

   An invoice is dated 2026-05-14 with terms "Net 30" (payment due 30 days after the invoice date). What is the due date?

   • A2026-06-13
   • B2026-06-15
   • C2026-06-12
   • D2026-06-14
   Show answer

   Answer: A. 2026-06-13

   May has 31 days: 17 days take you to May 31, and 13 more reach June 13. Adding "one month" (June 14) is a common mistake.

7. Question 7 of 18

   These invoices are waiting for payment. Which invoice number appears to have been received twice?

   Supplier	Invoice no.	Date	Amount ($)
   Westline Courier	WL-30812	2026-09-03	146.20
   Pinecrest Office Supply	PC-7741	2026-09-05	389.75
   Westline Courier	WL-30821	2026-09-10	146.20
   Pinecrest Office Supply	PC-7741	2026-09-05	389.75
   Ridge Plumbing	RP-1190	2026-09-12	612.00

   • ARP-1190
   • BWL-30821
   • CWL-30812
   • DPC-7741
   Show answer

   Answer: D. PC-7741

   PC-7741 appears twice with the same supplier, date and amount. The two Westline invoices have different numbers and dates, so they are separate bills.

8. Question 8 of 18

   Under the federal Input Tax Credit Information (GST/HST) Regulations, which detail is required on supporting documents only when the total is $500 or more?

   • AThe invoice date
   • BThe total amount paid or payable
   • CThe terms of payment
   • DThe supplier's name
   Show answer

   Answer: C. The terms of payment

   The supplier's name, the date and the total are required at every level. The terms of payment are added for totals of $500 or more.

9. Question 9 of 18

   Under the same regulations, from what total must supporting documents show the supplier's GST/HST registration number?

   • AAny amount, even under $100
   • B$100 or more
   • C$30 or more
   • D$500 or more
   Show answer

   Answer: B. $100 or more

   For totals of $100 or more, the documents must also show the registration number and the tax details. Under $100, they are not required.

10. Question 10 of 18

    Check the hours on this shift schedule. Whose hours are calculated incorrectly?

    Employee	Day	Start	End	Hours listed
    Aziz	Mon	07:00	15:00	8
    Brodeur	Mon	15:00	23:00	8
    Chan	Tue	06:30	14:30	8
    Dumont	Tue	14:00	22:30	9
    Ellis	Wed	09:00	17:30	8.5

    • AEllis
    • BAziz
    • CDumont
    • DChan
    Show answer

    Answer: C. Dumont

    14:00 to 22:30 is 8.5 hours, not 9. The other rows are correct.

11. Question 11 of 18

    A schedule uses the 24-hour clock. A shift runs from 19:00 to 03:00 the next morning. How long is the shift?

    • A4 hours
    • B16 hours
    • C22 hours
    • D8 hours
    Show answer

    Answer: D. 8 hours

    From 19:00 to midnight is 5 hours, and from midnight to 03:00 is 3 more: 5 + 3 = 8 hours.

12. Question 12 of 18

    A training schedule lists "Monday, 2026-11-10". What is the problem?

    • A2026-11-10 is a Sunday, so the day or the date is wrong
    • BThe date should be written 10-11-2026
    • CThere is no problem
    • D2026-11-10 is a Tuesday, so the day or the date is wrong
    Show answer

    Answer: D. 2026-11-10 is a Tuesday, so the day or the date is wrong

    November 10, 2026 falls on a Tuesday. When a day and a date are both given, check that they agree.

13. Question 13 of 18

    These are the bookings for one meeting room on the same day. Which two bookings overlap?

    Booking	Start	End
    A	09:00	10:30
    B	10:30	11:30
    C	11:15	12:00
    D	13:00	14:00

    • AA and B
    • BA and D
    • CB and C
    • DC and D
    Show answer

    Answer: C. B and C

    B runs until 11:30 but C starts at 11:15, so they overlap by 15 minutes. A ends at 10:30 exactly when B starts, so A and B do not overlap.

14. Question 14 of 18

    A site must have a guard on duty 24 hours a day. Based on this schedule, when is there no guard on duty?

    Shift	Start	End
    Day shift	07:00	15:00
    Evening shift	15:00	23:00
    Night shift	23:00	06:00

    • A15:00 to 16:00
    • B23:00 to 06:00
    • CThere is no gap
    • D06:00 to 07:00
    Show answer

    Answer: D. 06:00 to 07:00

    The night shift ends at 06:00 but the day shift starts at 07:00, leaving one hour with no one on duty.

15. Question 15 of 18

    An employee's timesheet shows daily hours and a total. What should the total be?

    Day	Hours
    Mon	7.5
    Tue	8
    Wed	6.5
    Thu	8
    Fri	7.5
    Total (as written)	38.5

    • A35.5
    • B36.5
    • C38.5
    • D37.5
    Show answer

    Answer: D. 37.5

    7.5 + 8 + 6.5 + 8 + 7.5 = 37.5 hours. The written total is 1 hour too high, so the timesheet must be corrected before payroll.

16. Question 16 of 18

    One line total on this invoice is wrong. After you fix it, what is the correct total including 5% tax?

    Item	Qty	Unit price ($)	Line total ($)
    Hand soap refill (case)	4	28.50	114.00
    Nitrile gloves (box)	15	9.80	174.00
    Bleach (4 L)	6	6.50	39.00

    • A$315.00
    • B$300.00
    • C$343.35
    • D$327.00
    Show answer

    Answer: A. $315.00

    Gloves: 15 × $9.80 = $147.00, not $174.00. The subtotal is $114.00 + $147.00 + $39.00 = $300.00, and $300.00 × 1.05 = $315.00.

17. Question 17 of 18

    • CIvanova
    • DJasper
    Show answer

    Hussein is scheduled on 6 days. Grant and Ivanova each have exactly 5, which is allowed, and Jasper has 4.

18. Question 18 of 18

    • A$90.00
    • B$120.00
    • C$210.00
    • D$36.00
    Show answer

    Answer: A. $90.00

    The invoice bills 84 − 48 = 36 units too many, and 36 × $2.50 = $90.00. The digits 4 and 8 were swapped.
