Elena and her husband Marc both drive to work. Elena’s car has a current mileage (total distance driven) of 11,000 and she drives 15,000 miles more each year. Marc’s car has a current mileage of 24,000 and he drives 8,000 miles more each year. Will the mileages for the two cars ever be equal?

Answer :

Answer:

After 13/7 miles.

Step-by-step explanation:

For Elena:

11000 - y-intercept

15,000 - slope

For Marc:

24000 y intercept

slope 8000

11000+15000x=8000x+24000

11000+7000x=24000

700x = 13000

x = 13/7
