Question

Amelia has a job baby-sitting for a neighbor. She is paid $20 plus $2.50 for each hour on the job. If Amelia wants to earn $40 to buy a new sweater, how many hours would she need to work?

Answer 1

Alright, so $20 is accounted for, and is half of $40. With only another $20 remaining, you can simply divide it by $2.50.

20 ÷ 2.50 = 8

20 + 2.50h = 40

h = 8

Amelia will have to work 8 hours to earn enough money to buy a new sweater.

Answer 2

8 hours is your answer
