# College 2

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

Correct result:

x =  60 miles

#### Solution:

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

Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
