What if it's f(m)=16.95+0.75 ?

Question

felipe rented a truck for one day. there was a base fee of $16.95,and there was an additional charge of 75 cents for each mile driven. felipe had to pay $157.95 when he returned to the truck.for how many miles did he drive the truck?

Answer 1

Let m = the number of miles Felipe drives and f(m) = the cost of driving m miles.

f(m) = $16.95 + ($0.75)m

If Felipe paid $157.95:

$157.95 = $16.95 + ($0.75)m

Solve for m.
