Answer the following question.
As a special treat, Georgia makes muffins and brings them to her students on the first day of every month. Her muffin recipe only makes 6 muffins and she has 24 students. How many batches of muffins does Georgia make in 9 months?
Step-by-step reasoning process: She has 24 students and her muffin recipe only makes 6 muffins so she needs to bake 24 / 6 = 4 batches of muffins. She brings muffins on the 1st of the month for 9 months and it takes 4 batches to feed all of her students so she bakes 9 * 4 = 36 batches of muffins.
The answer is 36.

Answer the following question.
You can buy 4 apples or 1 watermelon for the same price. You bought 36 fruits evenly split between oranges, apples and watermelons, and the price of 1 orange is $0.50. How much does 1 apple cost if your total bill was $66?
Step-by-step reasoning process: If 36 fruits were evenly split between 3 types of fruits, then I bought 36 / 3 = 12 units of each fruit. If 1 orange costs $0.50 then 12 oranges will cost $0.50 * 12 = $6. If my total bill was $66 and I spent $6 on oranges then I spent $66 - $6 = $60 on the other 2 fruit types. Assuming the price of watermelon is W, and knowing that you can buy 4 apples for the same price and that the price of one apple is A, then 1W = 4A. If we know we bought 12 watermelons and 12 apples for $60, then we know that $60 = 12W + 12A. Knowing that 1W = 4A, then we can convert the above to $60 = 12(4A) + 12A. $60 = 48A + 12A. $60 = 60A. Then we know the price of one apple (A) is $60 / 60 = $1.
The answer is 1.
