Question

The cost of a daily rental car is as follows: The initial fee is $39.99 for the car, and it costs $0.20 per mile. If Julie's final bill was $100.00 before taxes, how many miles did she drive?

Answer 1

Let's assume

she drives 'x' miles

we are given

The initial fee is $39.99 for the car

it costs $0.20 per mile

so, we can find total cost

total cost =39.99+0.20*x

we are given final bill is $100

so, we can set it equal

`100=39.99+0.20x`

now, we can solve for x

`100-39.99=0.20x`

`0.2x=60.01`

`x=300.05mile`

so,

she drives 300.05 miles..........Answer
