Alf · Answer 1

5weeks

Good! Since you want to find when both of you have the same amount of money, you can set the two expressions representing the money equal to each other. This gives the equation $700 - $35 per week • weeks = $450 + $15 per week • weeks. Solving the equation, you find that you will have the same amount of money in 5 weeks.

700 - 35w = 450 + 15wLet's flip this equation450 + 15w = 700 - 35wNow, add both sides by 35w450 + 50w = 700Subtract both sides by 45050w = 250Divide both sides by 50w = 5

Thus, it will take 5 weeks for you an your friend to have the same amount of money.
