What is the answer

Question

Plan 1 is a weekly salary of $600 plus 7% commission of sales. Plan 2 is a straight commission of 11% of sales. How much in sales must he make in a week for both plans to result in the same salary?

Answer 1

If S = Sales

Plan 1: 600 + .07S

Plan 2: .11S When we equate them 600 + .07S = .11s or .04S = 600

Then S = Sales = $15,000
