Q: Gwen received a $900 bonus at work and decided to invest this money in the stock market. She spent one-third of her bonus on stock A, one-third on stock B, and the remaining one-third on stock C.  After one year, stock A and stock B had doubled in value, while stock C had lost half of its value. At the end of the year, how much were Gwen's stocks worth, in dollars?
A: One - third of her bonus was $900 / 3 = $300. After one year, stock A doubled in value and was worth $300 * 2 = $600. After one year, stock B doubled in value and was worth $300 * 2 = $600. After one year, stock C had lost half its value and was worth $300 / 2 = $150. Altogether, at the end of the year, Gwen's stocks were worth $600 + $600 + $150 = $1350. The answer is 1350.
Question: Simon collected treasures on the beach during his summer vacation. He collected a bucket of pearly seashells, a jar full of smooth sea glass, and a bag of ten sand dollars. If the jar holds three times as many pieces of glass as the bag does sand dollars, and the bucket holds five times as many seashells as the jar holds pieces of glass, how many treasures did Simon find on the beach?
Answer: The jar holds 3 * 10 = 30 pieces of glass. The bucket holds 5 * 30 = 150 seashells. Simon found 10 + 30 + 150 = 190 treasures on the beach. The answer is 190.
[Question]A single line is worth 1000 points. A tetris is worth 8 times that much.  Tim scored 6 singles and 4 tetrises. How many points did he score?
[Answer]A tetris is worth 8 * 1000 = 8000 points. So he scored 4 * 8000 = 32000 points from tetrises. He also scores 6 * 1000 = 6000 points from singles. So in total he scores 32000 + 6000 = 38,000 points. The answer is 38000.
Q: Nick is asking all his co-workers to chip in for a birthday gift for Sandra that costs $100. The boss agrees to contribute $15, and Todd volunteers to contribute twice as much since he always has to one-up everyone. If the remaining 5 employees (counting Nick) each pay an equal amount, how much do they each pay?
A: First find Todd's contribution by doubling the boss's contribution: $15 * 2 = $30. Now subtract Todd and the boss's contributions to find out how much still needs to be paid: $100 - $30 - $15 = $55. Now divide the remaining cost by the number of employees to find the cost per employee: $55 / 5 employees = $11 / employee. The answer is 11.

She had 4 * 12 = 48 shirts to start with. She gives away 48 / 3 = 16. So she has 48 - 16 = 32 left. The answer is 32.
