yoanna has $240 in her saving account and she deposits $20 each week. matt has $600 in his saving account ans withdraws $40 each week. how many weeks will it take until they have the same amount of money

Respuesta :

Six weeks.

First make two equations:

Yoanna: 240 + 20x

Matt: 600 - 40x

Make the equations equal each other and solve.

60x = 360 (I subtracted 240 from both sides and added 40x to both sides)

x = 60 (Divided both sides by 60).
