Workkeys Math Practice Test

A customer pays with three five-dollar bills, five quarters, and two dimes. What is the total cost of the item being purchased?

1. $14.45

2. $15.45

3. $16.45

4. $17.45

The correct answer is: $16.45

To determine the total amount paid by the customer, let's break down the denominations they used: 1. **Five-dollar bills**: The customer used three five-dollar bills. Therefore, the total from the five-dollar bills is calculated as: \[ 3 \times 5 = 15 \text{ dollars} \] 2. **Quarters**: The customer also used five quarters. Since each quarter is worth $0.25, the total for the quarters is: \[ 5 \times 0.25 = 1.25 \text{ dollars} \] 3. **Dimes**: Additionally, the customer used two dimes. Each dime is worth $0.10, so the total for the dimes is: \[ 2 \times 0.10 = 0.20 \text{ dollars} \] Now, we can combine these amounts to find the total payment: \[ 15 + 1.25 + 0.20 = 16.45 \text{ dollars} \] Thus, the total amount paid by the customer is $16.45. This aligns with the choice that reflects the correct sum, making it the
