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 s
ruslelena [56]

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
