Question

The cost of renting a car is $85/wk plus $0.15/mi traveled during that week. An equation to represent the cost would be y = 85 + 0.15x, where x is the number of miles traveled. If your cost was $94.75, how many miles were you charged for traveling?

Answer 1

I was being charged for 65 miles

Explanation:

Given

`y = 85 + 0.15x`

Required

Find x when y = 94.75

Substitute 94.75 for y in
`y = 85 + 0.15x`

`94.75 = 85 + 0.15x`

Collect Like Terms

`0.15x = 94.75 - 85`

`0.15x = 9.75`

Solve for x

`x = (9.75)/(0.15)`

`x = 65\\`
