College 2

The college student is moving into a dormitory. The student rents a truck for $19.95 plus $0.99 per mile. Before returning the truck, the student fills the tank with gasoline, which costs $65.32. The total cost was $144.67. Using a linear equation, explain the process to find how many miles the student drove the truck

Correct answer:

x =  60 miles

Step-by-step explanation:

$$\begin{gathered} f(x)=19.95+0.99x \\ 144.67-65.32=19.95+0.99\cdot x \\ 0.99x=59.4 \\ x=\frac{59.4}{0.99}=60 \\ x=60=60\text{miles} \end{gathered}$$
