Problem 3: Suppose you drive a car 168 miles on one tank of gas. The tank holds 12 gallons of gas.
(Assume the car travels the same distance for each one gallon of gas)
The number of miles traveled varies directly with the number of gallons of gas you use.

a.
Write an equation that relates miles traveled to gallons of gas used. (Use any variable you like in
the equation.

b. low far can you drive with 3.7 gallons of gas? (Make sure to show the calculations you did to
determine this answer)
