Question

A prom ticket at Smith High School is $120. Tom is going to save money for the ticket by walking his neighbor’s dog for $15 per week. If Tom already has saved $22, what is the minimum number of weeks Tom must walk the dog to earn enough to pay for the prom ticket?

Answer 1

7 weeks

Explanation:

Answer 2

7 weeks

Explanation:

Let's start by finding the amount of money Tom still has to make. TO do this, we can do 120-22 = $98. Let's call the number of weeks x. When we write it as an equation, we get 15x=98. Solving for x, we get x=6.53, but we have to round up to the nearest integer due to the context of the problem. Therefore, the answer is 7 weeks. Hope this helps!
