Question

One family saves 800$ and puts aside 75$ each month. Another family saves 500$ ands puts aside 95$ each month. When will they both have the same amount saved?

Answer 1

Explanation:

y = 75x + 800

y = 95x + 500

x = number of months and y = total money

when will they have the same amount saved.....when will they be equal....so set them equal to each other and solve for x

75x + 800 = 95x + 500

800 - 500 = 95x - 75x

300 = 20x

300/20 = x

15 = x......so they will have the same amount in 15 months
