Answer this question:A wood stove burns 4 bundles of wood in the morning, then some more in the afternoon. If there were 10 bundles of wood at the start of the day and 3 bundles of wood at the end of the day, how many bundles of wood were burned in the afternoon?
Working out the difference between the amount of wood available at the start and the end of the day shows that 10 bundles 3 bundles = 7 bundles of wood have been burned throughout the day. Subtracting the wood burned in the morning from this shows that 7 bundles 4 bundles = 3 bundles of wood were burned in the afternoon.
The answer is 3.

Answer this question:It costs Molly $5 per package to send Christmas gifts to her relatives by mail. She has two parents and three brothers, and each of her brothers is married with 2 children each. If she sends one package to each relative by mail, how much does it cost her to send all of the gifts by mail to her relatives, in dollars?
Molly has two parents and three brothers, which totals 2 + 3 = 5 parents and siblings. Since each brother is married with 2 children, then each brother has a family containing 1 + 2 = 3 people. Thus, the families of the three brothers contain an additional 3 * 3 = 9 relatives. In total, Molly has 5 + 9 = 14 relatives. At $5 per package, Molly will spend 14 * $5 = $70 to mail the packages.
The answer is 70.

Answer this question:There are 248 pages in a book. Joanna can read 16 pages per hour. On Monday, she reads for 3 hours. On Tuesday, she reads for 6.5 hours. How many more hours does she need to read to finish the book?
On Monday, Joanna reads 3 * 16 = 48 pages. On Tuesday, Joanna reads 6.5 * 16 = 104 pages. So far, she has read 48 + 104 = 152 pages. Thus, she has 248 - 152 = 96 pages left. She will need to read for 96 / 16 = 6 hours to finish the book.
The answer is 6.
