The percentage change in the Amy’s hourly rate is 15 %.
Solution:
Given, Amy earns £10.00 per hour.
She gets a raise, and her new hourly rate is £11.50
We have to find what is the percentage change in her hourly rate?
The percentage change is given as:
[tex]\text { Percentage change }=\frac{\text { change in the value }}{\text { original value }} \times 100 \%[/tex]
Here original value = 10
Final value = 11.50
Change in value = Final value – Original value
Change in value = 11.50 – 10 = 1.5
Plugging in the values in formula we get,
[tex]\begin{array}{l}{\text { Percentage change }=\frac{1.5}{10} \times 100 \%} \\\\ {=1.5 \times 10 \%=15 \%}\end{array}[/tex]
Hence, the percentage change in the Amy’s hourly rate is 15 %.
