We have a question: If Alice purchased 3600 acorns for nine times the price Bob paid, and Bob paid $6000 for his acorns, how much money did Alice pay for each acorn?
And an answer: 15
So how you got the answer?
Nine times the price Bob paid for his acorns is 9 * $6000 = $54000. If Alice purchased 3600 acorns for nine times the price Bob paid, she paid $54000 / 3600 = $15 for each acorn.

We have a question: Ivan buys 48 apples to make 24 full-size pies. He ends up not using as many as he thought because he decides to make mini pies instead of full-size ones, which only use 1/2 an apple each. If Ivan bakes 24 mini pies, how many apples does he have leftover?
And an answer: 36
So how you got the answer?
Ivan wants to bake 24 pies which use 1 / 2 an apple each, 24 pies x 1 / 2 apple each = 12 apples. Ivan uses 12 of his 48 apples, 48 - 12 = 36 apples. Ivan has 36 apples leftover.

The sum is 9 + 14 + 13 = 36. There are 3 bouquets. The average is 36 / 3 = 12.
