Question

A salesperson at jewelry store earns 6% commission each week last week hendi sold $530 worth of jewelry How much did she make in commission? How much did the jewelry store earn in commission? I got both questions wrong and need an explanation of how

Answer 1

In this problem the store sold 530 dollars so this correspound to the 100 so we can calculate the 6% to know how much she make so we use a rule of three:

$\begin{gathered} 530\to100 \\ x\to6 \end{gathered}$

and the equation will be:

$\begin{gathered} x=\frac{530\cdot6}{100} \\ x=31.8 \end{gathered}$

So she earned $31.80 dollars in commission

and the store will made:

$530-31.8=498.20$
