Question 1

A clerk is tasked with ordering office supplies. They need to order 15 boxes of pens at $12.40 each, 25 notebooks at $3.50 each, and 5 printer cartridges at $45.00 each. What is the total cost of the order before sales tax?

Accepted Answer

$498.50

Answer

To find the total cost, you must calculate the cost for each item and then add them together. Pens: 15 * $12.40 = $186.00. Notebooks: 25 * $3.50 = $87.50. Cartridges: 5 * $45.00 = $225.00. Total Cost: $186.00 + $87.50 + $225.00 = $498.50.

Question 2

An employee works 37.5 hours per week at a rate of $18.00 per hour. If 18% of their gross pay is deducted for taxes and 4% is deducted for a retirement plan, what is their net pay for one week?

Accepted Answer

$526.50

Answer

First, calculate the gross pay: 37.5 hours * $18.00/hour = $675.00. Next, calculate the total deduction percentage: 18% + 4% = 22%. Then, find the total deduction amount: $675.00 * 0.22 = $148.50. Finally, subtract the deductions from the gross pay to find the net pay: $675.00 - $148.50 = $526.50.

Question 3

A department's budget was $12,500 for the quarter. They spent $4,500 on salaries, $2,750 on supplies, and $1,800 on utilities. What percentage of the budget remains?

Accepted Answer

27.6%

Answer

First, sum the total expenses: $4,500 + $2,750 + $1,800 = $9,050. Next, find the remaining amount: $12,500 - $9,050 = $3,450. Finally, calculate the percentage of the budget that remains: ($3,450 / $12,500) * 100 = 27.6%.

Question 4

Which of the following fractions is the largest: 3/4, 4/5, 7/8, 13/16?

Accepted Answer

7/8

Answer

To compare the fractions, convert them to decimals. 3/4 = 0.75. 4/5 = 0.80. 7/8 = 0.875. 13/16 = 0.8125. Comparing the decimal values, 0.875 is the largest, which corresponds to the fraction 7/8.

Question 5

A batch of 500 invoices needs to be processed. Clerk A can process 25 invoices per hour, and Clerk B can process 20 invoices per hour. If they work together, how many hours will it take them to process the entire batch?

Accepted Answer

11.1 hours

Answer

When working together, their combined processing rate is the sum of their individual rates: 25 invoices/hour + 20 invoices/hour = 45 invoices/hour. To find the total time required, divide the total number of invoices by their combined rate: 500 invoices / 45 invoices/hour ≈ 11.11 hours.
