\begin{gathered} A)18.90=2.25\text{e} \\ \text{samuel earns= \$ 8.40 per hour} \end{gathered}

Step-by-step explanation

Step 1

Let


\begin{gathered} \\ \text{total = numbers of hours}\cdot\text{ rate} \end{gathered}

then, Let

rate=e

total=18.90

numbers of hours=2.25

now, replace


\begin{gathered} \text{total = numbers of hours}\cdot\text{ rate} \\ 18.90=2.25\cdot e \\ 18.90=2.25e\rightarrow equation \\ \text{divide both sides by 2}.25\text{ to solve for e} \\ (18.90)/(2.25)=(2.25e)/(2.25) \\ 8.4=e \end{gathered}

hence, the rate is $ 8.4 per hour

I hope this helps you
