Answer the following question.
Adam and Tom are brothers. Adam is 8 years old and Tom is 12 years old. In how many years will their combined age be 44 years old?
Step-by-step reasoning process: At present, the two brothers have a combined age of 8 + 12 = 20 years old. Therefore, 1 year means an increase in the sum of their ages by 1 * 2 = 2 years. Adam and Tom need a total of 44 - 20 = 24 more years to be 44 years old together. So both brothers will be 44 years old together after 24 / 2 = 12 years.
The answer is 12.

Answer the following question.
A small theater company sells tickets to a show. They have a 400 seat theater and fill to 80% capacity. Each ticket cost $30. They repeated the same performance 2 other days. How much did they make?
Step-by-step reasoning process: They sold 400 * .8 = 320 tickets each day. So each day they made 320 * 30 = $9600. They did 2 + 1 = 3 days. So they made 9600 * 3 = $28,800.
The answer is 28800.

Answer the following question.
Angel has written letters to all of her pen pals and is putting all of the letters in envelopes. Most of the letters are put into large envelopes and the remaining 20 letters are put into small envelopes. The large envelopes each contain 2 letters each. If Angel has written a total of 80 letters, how many large envelopes did she use?
Step-by-step reasoning process: As some of the letters are in small envelopes, there must be 80 total letters – 20 letters in small envelopes = 60 letters in large envelopes. Angel therefore used 60 letters / 2 letters per large envelope = 30 large envelopes.
The answer is 30.

Answer the following question.
A craft store makes a third of its sales in the fabric section, a quarter of its sales in the jewelry section, and the rest in the stationery section. They made 36 sales today. How many sales were in the stationery section?
Step-by-step reasoning process: The craft store made 36 / 3 = 12 sales in the fabric section. It made 36 / 4 = 9 sales in the jewelry section. Thus, there were 36 - 12 - 9 = 15 sales in the stationery section.
The answer is 15.
