Question: A carnival snack booth made $50 selling popcorn each day. It made three times as much selling cotton candy. For a 5-day activity, the booth has to pay $30 rent and $75 for the cost of the ingredients. How much did the booth earn for 5 days after paying the rent and the cost of ingredients?
Answer with step-by-step thinking: The booth made $50 x 3 = $150 selling cotton candy each day. In a day, the booth made a total of $150 + $50 = $200. In 5 days, they made a total of $200 x 5 = $1000. The booth has to pay a total of $30 + $75 = $105. Thus, the booth earned $1000 - $105 = $895.
So the answer is 895.

Question: A craftsman makes 16 jars. This is exactly twice the number of clay pots he made. If each jar has 5 marbles and each clay pot has three times as many, how many marbles are there?
Answer with step-by-step thinking: 16 jars are exactly twice the number of clay pots made by the craftsman, meaning there are 16 / 2 = 8 clay pots. If each jar has 5 marbles, the total number of marbles in the jars is 5 * 16 = 80. Each of the clay pots also has 3 * 5 = 15 marbles. The total number of marbles in the 8 clay pots is 15 * 8 = 120. There are a total of 120 + 80 = 200 marbles.
So the answer is 200.

Question: In a bookstore, a book costs $5. When Sheryll bought 10 books, she was given a discount of $0.5 each. How much did Sheryll pay in all?
Answer with step-by-step thinking:
Instead of $5 each, a book costs $5 - $0.5 = $4.5 each. Sheryll paid $4.5 / book x 10 books = $45.
So the answer is 45.
