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

13%

Explanation:

Answer 2

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} (2500)/(100)=(350)/(x) \\ \text{cross multiply} \\ 2500x=350\cdot100 \\ 2500x=35000 \\ \text{divide both sides by 2500} \\ (2500x)/(2500)=(35000)/(2500) \\ x=14 \end{gathered}`

it means, the rate is 14%

I hope this helps you
