Answer :

Answer:

When we are given a flat fee and a rate, in this case $100 and $0.19 respectively, it means that the amount that we pay starts at $100, then increases by $0.19 per mile. As an equation, this can be written as:

Rental Fee = 0.19X + 100

Since X is the number of miles driven, we can solve for the cost of driving 50 miles by substituting it in for X in the equation:

Rental Fee = 0.19(50) + 100 = $109.50

The cost of a rental and driving for 50 miles is $109.50.
