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 :
[tex]\dfrac{\text{Increase in hourly pay}}{\text{Previous Hourly pay}}\times100\%\\\\=\dfrac{0.70}{7}\times100\%\\\\=\dfrac{1}{10}\times100\%\\\\=10\%[/tex]
Hence, the percent increase in her hourly rate of pay = 10%
