Jake is saving money for his first car. He works as a lifeguard at the Lee District Rec Center and gets paid $9.35 an hour. So far, he has already saved $1220. If he needs at least $5100 to buy the car, how many hours will he need to work?

1220/9.35 = 130.4 hours
$ he needs - $ he has:
5100 - 1220 = 3,880

The $ he still need/$he gets paid per hour:
3,880/9.35 =414.9
He will need to work 415 more hours.

130 + 415 = 545 total hours

** I don’t understand if you need to get how many more hours he needs to work or the full total of hours.
