Question

You earn a monthly salary of $1000 plus a 2% commission on your total sales for the month. Your total sales for this month were $10,500. What were your total earnings for this month?

Answer 1

e(s)=(2s/100)+1000 (earnings as a function of sales)

e(s)=0.02s+1000

So the earnings when sales are 10500 is:

e(10500)=0.02(10500)+1000

e(10500)=$1210.00
