There are 50 apples and 40 oranges in the cafeteria. If an apple costs $0.80 and an orange costs $0.50, how much does the cafeteria earn for apples and oranges if there are only 10 apples and 6 oranges left? Give the rationale and then the answer.
Let's think step by step. Counting the remaining 10 apples. There were 50 - 10 = 40 apples sold. Counting the remaining 6 oranges. There were 40 - 6 = 34 oranges sold. The amount of sales for the apples is $0.8 x 40 = $32. The amount of sales for the oranges is $0.5 x 34 = $17. The cafeteria's total earnings are $32 + $17 = $49.. The answer is: 49.

One batch of cookies requires 4 cups of flour and 1.5 cups of sugar. How many cups of flour and sugar combined would be needed for 8 batches? Give the rationale and then the answer.
Let's think step by step. Flour + sugar = 4 + 1.5 = 5.5 cups. 8 batches = 5.5 * 8 = 44 cups. There would be 44 cups of flour and sugar combined for 8 batches of cookies.. The answer is: 44.

Hannah is making banana bread. She needs to use 3 cups of flour for every cup of banana mush. It takes 4 bananas to make one cup of mush. If Hannah uses 20 bananas, how many cups of flour should she use? Give the rationale and then the answer.
Let's think step by step. First find the number of cups of banana mush Hannah gets: 20 bananas / 4 bananas / cup = 5 cups. Then multiply the number of cups of mush by the ratio of flour to mush to find the number of cups of flour: 5 cups mush * 3 cups flour / 1 cup mush = 15 cups flour.. The answer is: 15.
