Question

A salesman earns a commission of $350 for selling $2500 in merchandise. Find the commission rate. Write your answer as a percentage.

Answer 1

14%

Explanation

we can solve this by using a rule of three

let x represents the rate commision( in percentage)

so

if

$2500\rightarrow100\text{ \%}$

then

$350\rightarrow x$

now, set the proportion and solve for x

$\begin{gathered} \frac{2500}{100}=\frac{350}{x} \\ \text{cross multiply} \\ 2500x=350\cdot100 \\ 2500x=35000 \\ \text{divide both sides by 2500} \\ \frac{2500x}{2500}=\frac{35000}{2500} \\ x=14 \end{gathered}$

it means, the rate is 14%

I hope this helps you
