Question

chris can be paid in one of two ways. plan a is a salary of $450 per month, plus a commission of 8% of sales. Plan B is a salary of $760 per month, plus a commission of 3% of sales. For what amount of cells is Chris better off selecting plan A?

Answer 1

450+.08x=760+.03x
450+.08x-.03x=760+.03x-.03x
450+.05x=760
450-450+.05x=760-450
.05x=310
.05x/.05=310/.05
x=6200
so for 6200 in sales either plan is the same
so for any amount of sales more than 6200 you are better off picking Plan A.
