Question

The basketball team rented a bus for and out of town trip. the cost was $315 plus $0.45 per mile. if the total was $342, how many miles was the trip?

Answer 1

60 miles

Explanation:

The basic equation is:

Fixed Cost + Variable Cost = Total Cost

The Fixed Cost = 315

The Variable Cost = 0.45x [where x is the number of miles]

The Total Cost = 342

Now, we write these in place of the original equation and get our mathematical equation to solve for x:

`315+0.45x=342`

Now, we simply solve for x:

`315+0.45x=342\\0.45x = 342 - 315\\0.45x = 27\\x=(27)/(0.45)\\x=60`

The trip was 60 miles
