WRITE A PROPORTIAN THAT IS EQUIVALENT TO THE STATMENT : IF 3 GALLONS OF GASOLINE COST $5.37, THEN 8 GALLONS WILL COST $ 14.32.
3 gallons/$5.37 = 8 gallons/$14.32
(you can easily test if a proportion that you wrote is true by taking the cross-products. These cross-products should be equal.
i.e. 3x14.32 = 8x5.37 )
