13. To rent a car, you pay a one-time charge of $45 plus a charge of $0.29 for
deff fn [24]

Answer:

<em>The correct choice is (c) $79.80</em>

Step-by-step explanation:

The total charge for renting a car can be split into two parts:

A fixed one-time charge of $45

A variable charge of $0.29 per driven mile.

If I drive 120 miles, the variable charge will be 120*0.29 = $34.80

The total charge will be $45 + $34.80 = $79.80

The correct choice is (c) $79.80
