Problema Solution

each month you earn $2200.00 plus one fifteenth of your sales. What must your sales be this month to earn $4000.00

Answer provided by our tutors

let your sales be s

you earn: 2200 + (1/15)s

you want this to equal 4000, so you have the equation:

4000 = 2200 + (1/15)s subtract 220 from both sides

1800 = (1/15)s multiply both sides by 15

27000 = s

so your sales need to be $27,000
