You want to save the money to buy your own cell phone. You have already saved $80. You plan to save
an additional $9.50 per week. If the phone costs
$118.00, how many weeks will you have to save $9.50
before you have enough money to buy the phone?

The tuition costs, c, for a local community college are modeled by c(h) = 250 + 200h, where h represents the number of credit hours taken. the local state university has tuition costs, s, modeled by the function s(h) = 300 + 180h. how many credit hours will a student have to take for the two tuition costs to be equal? round the answer to the nearest tenth of an hour.

This is so hard and it’s for a test
