Answer:

C) 15 days

Explanation:

To answer this question, we must make an equation, so lets use the variable 'd' equal the number of days a car is being used for:

22d + 100 = 26d + 40

Now, we combine like terms:

22d + 100 = 26d + 40

-22d -22d

100 = 4d + 40

-40 -40

60 = 4d

/4 /4

d = 15

So, the rental cost will be the same for both car companies after 15 days

Hope this helps :)
