Fred’s car gets 36 miles per gallon on highways and 26 miles per gallon when driving in cities. If Fred has a 12-gallon tank, how many miles can he travel in the city before having to refill his tank?

12 gallons x 26 miles per gallon = 312

Fred can travel up to 312 miles

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
