Which equation andsolution represents e, the amount Samuel earns each hour at his job?A)18.90 = 2.25eSamuel earns $8.40 per hour.B)2.25 = 18.90eSamuel earns $8.40 per hour.C) 2.25 = 18.90eSamuel earns $42.53 per hour.D)18.90 = 2.25eSamuel earns $42.53 per hour.

Answer 1

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

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

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

hence, the rate is $ 8.4 per hour

I hope this helps you
