Respuesta :

Here is a pattern, 78:67, 84:63, 90:59, 96:55, 102:51. So it took 4 times to get there.

Answer:

After 4 months number of SUVs rented will be twice the number of compact cars rented.

Step-by-step explanation:

Tom's car rentals rented 78 SUVs and 67 compact cars.

The number of SUV's rented by Tom's Car Rentals has been increasing by 6 every month and number of compact cars are decreasing by 4.

Let after x months the number of SUVs rented will be twice of the compact cars rented.

Number of SUVs rented after x months = 78 + 6x

Number of compact cars rented after x months = 67 - 4x

78 + 6x = 2(67 - 4x)

78 + 6x = 134 - 8x

6x + 8x = 134 - 78

14x = 56

x = 4

Therefore, after 4 months number of SUVs rented will be twice the number of compact cars rented.
