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 and by babysitting his little brother for $22 a week.

Which equation can be used to find the minimum number of weeks Tom must walk the dog (x) and babysit his little brother (y) to earn enough to pay for the prom ticket?

15x+22y≥120

15x+22y≥120

15x−22y≤120

15 x minus 22 y is less than or equal to 120

15x≥120+22y

15 x is greater than or equal to 120 plus 22 y

15x−22y≤120

15 x minus 22 y is less than or equal to 120
