Olga worked 37.5 hours last week at the library and earned 12.50 an hour. if she gets a 2.50 per hour raise, how many hours will she have to work to make the same amount of money as she did last week?

Olga worked 37.5 hours last week and earned $12.50 an hour.

[ h = the number of hours              y = total earnings ]

12.50h = y

12.50(37.5) = y

468.75 = y

She earned $468.75 last week

If she gets a $2.50 per hour raise:

12.50 + 2.50 = 15.00

She gets $15 per hour.

How many hours will she have to work to make $468.75?

15h = 468.75        Divide 15 on both sides to get "h" by itself

h = 31.25

She needs to work 31.25 hours
