1The following situation can be modeled by a linear function. Write an equation for the linear function and use it to answer the given question. Be sure you clearly identify the independent and dependent variables. Is a linear model reasonable for the situation described?

You can rent time on computers at the local copy center for a

a $6

6 setup charge and an additional $2.75

2.75 for every 5

5 minutes. How much time can be rented for $24

24?

Select the correct choice below and fill in the answer box to complete your choice.

A.

The independent variable is time (t), in minutes, and the dependent variable is rental cost (r), in dollars. The linear function that models this situation is r equals?

.

(Simplify your answer. Do not include the $ symbol in your answer.)

B.

The independent variable is rental cost (r), in dollars, and the dependent variable is time (t), in minutes. The linear function that models this situation is t equals ?

(Simplify your answer. Do not include the $ symbol in your answer.)
