Arlene sells computers and tables. she earns 8% commission on every dollar of sales that she makes

I attached a screenshot for the complete question.

equation is: 0.08x = 2560
Total sales = $32,000

Explanation:
Assume that the total sales for the month is x.

Now, we are given that:
Her commission is 8% for each dollar and that she made a total of $2560 in commission.
This means that:
8% of x = 2560
8% * x = 2560
0.08x = 2560 ...........> required equation

Now, after getting the equation, we can solve for x to get the total sales as follows:
0.08x = 2560 
x = 2560 / 0.08
x = 32,000

This means that her total sales for the month is $32,000

Hope this helps :)

It is a percent with money involved too divide and you should have your answer
