[Question]: 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?
[Answer]: Javier ate 7.5 ounces of meat ravioli because 5 x 1.5 = 7.5. He ate 2.5 ounces of pumpkin ravioli because 2 x 1.25 = 2.5. He ate 4 ounces of cheese ravioli because 4 x 1 = 4. Javier ate 14 ounces in total because 7.5 + 2.5 + 4 = 14. His brother ate 15 ounces of pumpkin ravioli because 12 x 1.25 = 15. The winner ate 15 ounces in total because 15 > 14.
So the answer is 15.

[Question]: Chip has a $50.00 balance on his credit card. Since he didn't pay it off, he will be charged a 20% interest fee. He puts $20.00 on his credit card the following month and doesn't make any payments to his debt. He is hit with another 20% interest fee. What's the current balance on his credit card?
[Answer]: He has a balance of $50.00 and is charged 20% interest so that's 50 * .20 = $10.00. He had a balance of $50.00 and now has a $10.00 interest fee making his balance 50 + 10 = $60.00. His balance is $60.00 and he puts another $20.00 on his card for a total of 60 + 20 = $80.00. He didn't make a payment that month and is hit with another 20% interest fee so that's 80 * .20 = $16.00 in interest. His new balance is 80 + 16 = $96.00.
So the answer is 96.

He started with 2 * 4 = 8 trees. He plants trees for 15 - 10 = 5 years. So he planted 5 * 4 = 20 trees. So he had 20 + 8 = 28 trees. After doubling them he had 28 * 2 = 56 trees.
So the answer is 56.
