Question

Charmaine has 17 cars available to rent. Let C be the number of cars she would have left after renting R of them.

Answer 1

C = 17 - R

Explanation:

In this scenario, 17 cars would be the initial starting point. While C would be the final number of cars, meaning that our equation would have to equal C. If she rents R number of cars then this number is being subtracted from the initial number of cars because Charmaine would no longer have them in his/her possession. Therefore, it is being subtracted. Using this information we can create the following equation.

C = 17 - R
