22. mp make a prediction a speed limit of 100 kilometers per hour (kph) is
approximately equal to 62 miles per hour (mph). write an equation
relating kilometers per hour k to miles per hour m. then predict the
following measures. round to the nearest tenth.
a. a speed limit in mph for a speed limit of 75 kph
b. a speed limit in kph for a speed limit of 20 mph

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.
