a. Set up a linear model to calculate a student's bill based on this information.

b. How much would it cost to take 15 credit hours. DO NOT use a dollar sign in your answer.

c. Use your model to determine how many credit hours a student is taking if his bill is $1639.50.

Answer 1

Hello Sir/ mam

Given that:

Student have to pay technology fee of $60, which is fixed and $121.5 per credit hour, which means variable.

Let the student's bill be Y and total number of credit hours be X.

(a)

Linear Model:

Y = 121.5x + 60

(b) If X = 15,

then

Y = (121.5*15) + 60 = 1882.50

(c)

Tota Bill = 1639.50

Hence,

1639.50 = 121.5x + 60

1579.5 = 121.5x

x = 13 hours
