Crystal wanted to sell everything left in her pastry class before closing for the night. She reduced her $3.00 cupcakes and her $2.00 cookies by half. How much money did she make if she sold the last 16 cupcakes and 8 cookies?
Let's think: She reduced the price of the $3.00 cupcakes by half so they are now 3 / 2 = $1.50. She reduced the price of the $2.00 cookies by half so they are now 2 / 2 = $1.00. She sold 16 cupcakes at $1.50 each so she made = 16 * 1.50 = $24.00. She sold 8 cookies at $1.00 each so she made 8 * 1 = $8.00. She made $24.00 from the cupcakes and $8.00 from the cookies for a total of 24 + 8 = $32.00.. The answer is: 32.

If Jim has 20 apples, and Jane has 60 apples, and Jerry has 40 apples, how many times can Jim's number of apples fit into the average amount of apples for a person in the group?
Let's think: First, we need to find the average number of apples per person. We start by adding the three totals together, getting 20 + 60 + 40 = 120 apples. To finish finding the average number, we perform 120 / 3 = 40 apples per person. Since Jim has 20 apples, we divide the average of 40 by Jim's total to find 40 / 20 = 2 times that Jim's amount can fit into the average.. The answer is: 2.

Hallie borrows a book from the library. She reads the entire book in four days. She read 63 pages the first day. On the second day, she read twice the number of pages that she'd read on day one. On the third day, she read 10 mores pages than she read on day two. If the book is 354 pages long, how many pages did she read on the fourth day?
Let's think: On day two, she read 63 * 2 = 126 pages. On day three, she read 126 + 10 = 136 pages. On day four, she read 354 - 63 - 126 - 136 = 29 pages to finish the book.. The answer is: 29.

Sarah's age is equal to three times Mark's age minus 4. Mark is four years older than Billy. Billy is half Ana's age. If Ana will be 15 in 3 years, how old is Sarah?
Let's think:
First figure out how old Ana is right now by subtracting 3 from 15: 15 - 3 = 12. Next, figure out how old Billy is by dividing Ana's age by 2: 12 / 2 = 6. Now figure out how old Mark is by adding 4 to Billy's age: 6 + 4 = 10. Now, to figure out Sarah's age, first multiply Mark's age by 3: 10 * 3 = 30. Finally, subtract 4 from triple Mark's age to find Sarah's age: 30 - 4 = 26.. The answer is: 26.
