A is correct because if you subsitute 5 for d or days, you get 140 for both equations

B is obviously wrong because a positive number of days + 20 is not more than 5 for charlie's car rentals

C is wrong because we saw that in 5 days, the car companies earn equal ammounts

D is wrong because we saw that in 5 days, the car companies earn equal ammounts
