Question

A salesperson earns a commission of $532 for selling $2800 in merchandise.Find the commission rate. Write your answer as a percentage.

Answer 1

Hello! To solve this exercise, we have to use the rule of three, look:

Let's consider:

• $2800 is the full value, so, 100%

,

• $532 is the commission, as x %

`\begin{gathered} (2800)/(532)=(100)/(x) \\ \\ \text{multiplying accross} \\ 2800\cdot x=532\cdot100 \\ 2800x=53200 \\ \\ x=(53200)/(2800) \\ \\ x=19 \end{gathered}`

So, the commission rate is 19%.
