Step-by-step explanation:well at 15$ a week and he already has saved 22$ so if he does that for about 5 or 6 more weeks he should have

Answer: the minimum number of weeks is 7

Step-by-step explanation:

Let x represent the number of weeks that Thomas walk the dog.

Tom is going to save money for the ticket by walking his neighbor's dog for $15 per week. if Tom already has save $22, it means that the total amount that he would have saved if he walks the dog for x weeks is

15x + 22

A prom ticket at Smith high school is $120. Then, the expression for the minimum number of weeks that Thomas would walk the dog to earn enough to pay for the prom ticket is

15x + 22 ≥ 120

15x ≥ 120 - 22

15x ≥ 98

x ≥ 98/15

x ≥ 6.5

Since the number of weeks must be whole number, then x = 7
