Given:
Monthly pay = $2490
Commission on sales = 9%
Sales for last month = $88,000
Let's find the commission and gross pay for last month.
To find the commission, apply the formula:
Commission for last month = 9% of sales for last month
Thus, we have:
Commission for last month =
![\begin{gathered} (9)/(100)\ast88000 \\ \\ =0.09\ast88000 \\ \\ =7920 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/442o5h06ob8b4181aqkrn3i4ikyhpmkv1g.png)
Therefore, the commission for last month is $7,920.
To find the gross pay, apply the formula:
Gross pay = Monthly salary + Commission amount
Gross pay = $2490 + $7920 = $10,410
Therefore, the gross pay for the month is $10,410
ANSWER:
Commission = $7920
Gross pay = $10410
