Answer 1

Answer:

$18.40

Explanation:

Last month, Karmin made $480 working for 30 hours.

Therefore, the amount she earns per hour will be:

$\begin{gathered} =\frac{480}{30} \\ =\ 16\text{ per hour} \end{gathered}$

We are told that this month, she will get a 15% increase in the amount she earns per hour.

Therefore, her hourly rate after the raise will be:

$\begin{gathered} =16+(15\%\text{ of 16)} \\ =16+(0.15\times16) \\ =16+2.4 \\ =\ 18.40 \end{gathered}$
