Atree house costs $530. you plan to save $10 each week. your parents will pay $80 of the cost. your savings plan can be modeled with the equation s = 10w + 80. after how many weeks will you be able to afford the tree house?

The answer would be 45 weeks, since you do 530-80 since that is the part the parents will foot, which will be 450 left. Then you do that divided by 10 since you plan to save 10 dollars a week and therefore are left with 45 weeks.
