[Question]Gerald is a furniture maker. He has 672 pieces of wood and he wants to make some tables and chairs. It takes 12 pieces of wood to make a table and 8 pieces of wood to make a chair. How many chairs can he make if he makes 24 tables?
[Answer]Each table takes 12 pieces of wood to make so 24 tables will take 24 * 12 = 288. There were originally 672 pieces of wood so now there are 672 - 288 = 384 pieces left. 8 pieces of wood make 1 chair so 384 pieces can make 384 / 8 = 48 chairs. The answer is 48.

Question: Yoque borrowed money from her sister. She promised to pay it back in 11 months including an additional 10% of the money she borrowed. If she pays $15 per month, how much money did she borrow?
Answer: In 11 months, Yoque will pay a total of $15 x 11 = $165. The amount $165 is 100% + 10% = 110% of the money she borrowed. So, 1% is equal to $165 / 110 = $1.50. Hence, Yoque borrowed $1.50 x 100 = $150. The answer is 150.
[Question]Pat's stick is 30 inches long. He covers 7 inches of the stick in dirt. The portion that is not covered in dirt is half as long as Sarah's stick. Jane's stick is two feet shorter than Sarah's stick. How many inches long is Jane's stick?
[Answer]30 - 7 = 23 inches of Pat's stick is not covered in dirt. Sarah's stick is 23 * 2 = 46 inches long. Jane's stick is 12 * 2 = 24 inches shorter than Sarah's stick. Jane's stick is 46 - 24 = 22 inches long. The answer is 22.
