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.

250 + 200h = 300 + 180h
250 + 200h = 300 + 180h
− 180h − 180h
250 + 20h = 300

Respuesta :

Using linear functions, it is found that the student will have to take 2.5 credit hours for the  two tuition costs to be equal.

What is a linear function?

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

The costs for both plans are given by:

  • 250 + 200h.
  • 300 + 180h.

The costs will be the same when:

250 + 200h = 300 + 180h

Then:

20h = 50.

h = 50/20

h = 2.5.

The student will have to take 2.5 credit hours for the  two tuition costs to be equal.
