Justin rented a truck for one day. There was a base fee of , and there was an additional charge of cents for each mile driven. Justin had to pay when he returned the truck. For how many miles did he drive the truck?

This question is incomplete because the numbers are missing, so i will solve it in a general way where you can replace the values.

"Justin rented a truck for one day. There was a base fee of A, and there was an additional charge of B cents for each mile driven. Justin had to pay P when he returned the truck. For how many miles did he drive the truck?"

Ok, we can model the cost as a function of x, where x is the number of miles driven.

C(x) = A + B*x

Where A is the fee that is paid only one time, and B is the amount that he should pay for each mile driven.

Now, we know that he had to pay P when he returned the truck, then we should solve the equation:

A + B*x = P

We must solve this for x.

x = (P - A)/B

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x
