14. Monica and Ralph are driving a car that gets 12 miles per gallon.
       How far can they travel if they have a total of $48 to spend on gasoline, assuming that gasoline
       cost $2.00 per gallon.

 Solution: 
             $48 to spend on gasoline
             Gasoline cost $2.00 per gallon

             48/2 = 24 gallon, with $48 they get 24 gallon
             But the car gets 12 miles per gallon, then (12)(24) = 288 miles
