Answer:
Commission rate is 20%.
Explanation:
Joey's weekly salary is $325
Plus a commission on his total sales.
Let commission is x% on his total sales.
So, we can set up equation for the given information as
325+x%(2950)= 915
Solve this equation for x%.
Subtract both sides 325
x%(2950) =590
Divide both sides by 2950
x%=0.2
We know x% means it is
![(x)/(100)](https://img.qammunity.org/2022/formulas/mathematics/college/ecr6cc8ia3plpfl27r28u4bux97uo6ol81.png)
So,
![(x)/(100) =0.2](https://img.qammunity.org/2022/formulas/mathematics/high-school/qnaxa0xa9421q8qzd183bbleubdwtxc6ts.png)
Multiply both sides by 100
x=20%.
So, commission rate is 20%
