Question

Tamanika received a raise in her hourly pay, from $15.50 to $18.29. Find the percent change.

Answer 1

Given:

Old pay per hour = $15.50

New pay per hour = $18.29

Required: Percent change

Explanation:

Change in payment = 18.29 - 15.50 = 2.79

Percent change

$\begin{gathered} =\frac{\text{ Change in payment}}{\text{Old pay per hour}}\cdot100 \\ =\frac{2.79}{15.50}\cdot100 \\ =18\% \end{gathered}$

Final Answer: Percent change = 18%
