Marine fuel is a combination of gasoline and motor oil. The standard gasoline and oil mixture is about 98% gasoline and about 2% motor oil. The "break-in" mixture for a new engine is about 96% gasoline and about 4% motor oil. a. Write an equation in standard form that models the possible combinations of each kind of mixture you can prepare using 6 gallons of gasoline. b. If you prepare 4 gallons of the "break-in" mixture, how much gasoline will you have for the standard mixture? c. How much oil do you need to prepare 4 gallons of the "break-in" mixture? d. Oil is typically sold in fluid ounces. Use the fact that 128 fluid ounces = 1 gallon to convert your answer to part (c) to fluid ounces.
