3.3.PS-14 : Question Help A salesperson at a jewelry store earns 7% commission each week. Last week, Jarrod sold $530 worth of jewelry. How much did he make in commission? How much did the jewelry store make from his sales?

Answer 1

Since Jarrod earns 7% commising, then we can use the following expression:

$\begin{gathered} \text{Total earned}\cdot\frac{percent}{100}=equivalent\text{ number to the percent} \\ 530\cdot\frac{7}{100}=37.1\text{ usd} \end{gathered}$

He earn $37.1 last week.

530-37.1=$492.9 -> The jewelry store make $492.9 from his sales
