Question

Janis earns $7.00 per hour at Pizza King. After 6 months, her hourly rate of pay increased to $7.70 per hour. What is the percent increase in her hourly rate of pay?

Answer 1

Find the amount of the increase and divide that by the original amount:

7.70 - 7.00 = 0.70 increase

0.70 / 7.00 = 0.1

Multiply by 100 to get the percentage:

0.1 x 100 = 10 %

The increase was 10 %
