Question

A dance instructor earns $75 for teaching 3 classes. The instructor receives 10% raise. Enter how much the instructor earns, per class, after the raise.

Answer 1

Let's calculate the new earning per class after the 10% raise:

1. First, we need to find out how much the instructor earns per class before the raise: $75 / 3 classes = $25/class

2. Next, we need to calculate the 10% raise: $25 * 10% = $2.5

3. Finally, we add the raise to the original earning per class: $25 + $2.5 = $27.5

After the 10% raise, the dance instructor earns $27.5 per class.
