Question

A car rental company rented out 9 cars in its first month. The number of cars it rented doubled each month.

What was the total number of cars the company rented out for the first 5 months?

Answer 1

144 cars

Explanation:

well for month 1 is 9

month 2 would be 9 times 2 so 18

month 3 then you double that so 18 plus 18 is 36

month 4 next you'll double 36 so 36 plus 36 is 72

month 5 finally you double 72 so that equals 144 cars

Answer 2

9 cars=1 month.

18 cars= 2 months

36 cars= 3 months

72= 4 months

144= 5 months.

Add all cars which gives you a sum of 279 cars.
