Question

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

Answer 1

Answer: 10%

Explanation:

Given: Previous Hourly pay=  $7.00

Current Hourly pay = $7.70

Increase in hourly pay = Current Hourly pay  - Previous Hourly pay

= $7.70- $7.00

= $0.70

Now, the percent increase in her hourly rate of pay will be :

$\dfrac{\text{Increase in hourly pay}}{\text{Previous Hourly pay}}\times100\%\\\\=\dfrac{0.70}{7}\times100\%\\\\=\dfrac{1}{10}\times100\%\\\\=10\%$

Hence, the  percent increase in her hourly rate of pay = 10%
