Can you guide me through solving this problem: Javier is having an eating contest with his brother. It's ravioli night and there is meat ravioli, pumpkin ravioli, and cheese ravioli. The meat ravioli weighs 1.5 ounces each. The pumpkin ravioli is 1.25 ounces each. The cheese ravioli is one ounce. Javier eats 5 meat ravioli, 2 pumpkin ravioli, and 4 cheese ravioli. His brother just ate pumpkin ravioli and had 12 of them. What is the total amount of ounces eaten by the winner?
