Question

4. Sue and Ann earned the same amount of money, although one worked 6 days more than the

other. If Sue earned $36 per day and Ann earned $60 per day, how many days did each work?

Answer 1

Create a system of equations
36S = 60A
S = A + 6

Substitute
36(a + 6) = 60a
36a + 216 = 60a
216 = 24a
a = 9

Ann worked 9 days, Sue worked 15 days

Check
36(15) = 60(9)
540 = 540
