Question

Nick, a mattress salesman, earns a base salary of $2,000 per month and a 5% commission on all of his sales. If he earned $2,350 in June, how much did he sell?

Answer 1

if s = amount of sales (in dollars), then

E = 2000 + 0.05s

where E is the amount Nick earns

Answer 2

So "If he earned $2,350 in June", then E = 2350

Answer 3

which means we can say

E = 2000 + 0.05s

2350 = 2000 + 0.05s

Answer 4

Keep going to solve for 's'
