Joe received an hourly wage of $8.15. His boss gave him a 7% raise. How much does Joe make per hour now?

• A. $0.57
• B. $8.90
• C. $8.72
• D. $13.85

Answer: (C)

To determine how much Joe makes per hour after receiving a 7% raise, we first need to calculate the amount of the raise based on his current hourly wage of $8.15. First, we find 7% of $8.15. This can be calculated by multiplying Joe's hourly wage by 0.07: \[ 8.15 \times 0.07 = 0.5705 \] Next, we add this amount to Joe's original wage to find his new wage: \[ 8.15 + 0.5705 = 8.7205 \] For practical purposes, we typically round this to two decimal places, which gives us $8.72. This calculation shows that after the 7% raise, Joe's new hourly wage amounts to $8.72, distinguishing it as a fair representation of his increased earnings.
