Q: To raise money, a school is selling ice-pops for $1.50. It costs 90 cents to make each pop, and the money from the pops will be used to buy pencils, which cost $1.80 each. How many pops must be sold to buy 100 pencils?
A: To buy 100 pencils the school needs 100 * $1.80 = $180.00. Each ice pop sells for $1.50 but costs $.90 to make, for a net profit of $1.50 - $.90 = $.60. So in order to raise $180.00, the school will need to sell $180.00 / $.60 per ice - pop = 300 ice - pops. The answer is 300.
Question: A small pizza can gives 4 slices, and a large pizza gives 8 slices. George purchased 3 small and 2 large pizzas. George would like to eat 3 pieces. His friend Bob would like to eat one more piece than George. Susie will eat half as many as Bob. Bill, Fred and Mark would each like 3 pieces. How many slices of pizza will be left over?
Answer: George has 3 small pizzas * 4 slices = 12 pieces. George also has 2 large pizzas * 8 slices = 16 slices. Total, George has 12 + 16 slices = 28 slices of pizza. Bob will eat 3 slices + 1 = 4 slices. Susie will eat 1 / 2 * 4 slices = 2 slices. Bob, Fred and Mark will eat in total 3 + 3 + 3 = 9 pieces. Total slices of pizza eaten will be 3 + 4 + 2 + 9 = 18 pieces. Total pizza slices remaining will be 28 pieces - 18 = 10 slices left. The answer is 10.
[Question]48 children are trying to share a pack of sweets. After taking 4 sweets each, there is still a third of the original amount left. What is the original number of sweets in the pack?
[Answer]48 children took 4 each for a total of 48 * 4 = 192 sweets. If there is 1 / 3 left then 192 is 1 - (1 / 3) = 2 / 3 of the original amount (The whole packet minus 1 third). Therefore 192 is 2 / 3 of the original amount: (2 / 3) * original amount = 192. Multiplying both sides of the equation by (3 / 2) gives: original amount = 192 * (3 / 2) = 288. The answer is 288.
Q: Jamie collects glass balls. He had 16 red balls and two times more blue balls. Later on, he lost 6 of the red balls, so he decided to buy some yellow balls to fill up his collection. How many yellow balls did he buy if, after all, he had 74 balls in total?
A: Jamie had two times more blue balls than red ones, so he had 2 blue / red * 16 red balls = 32 blue balls. He lost 6 red balls so he had only 16 red balls - 6 red balls = 10 red balls. In total he had 32 blue balls + 10 red balls = 42 red and blue balls. He bought 74 balls - 42 red and blue balls = 32 yellow balls. The answer is 32.

Q: From his apartment, Kona drives 9 miles to the bakery. From there, he drives 24 miles to his grandmother’s house. From her house, he drives 27 miles straight to his apartment. How many additional miles did Kona drive round trip to the bakery stop, compared to a round trip without the bakery stop?
A:
With the bakery stop, Kona drove a total of 9 + 24 + 27 = 60 miles. Without the bakery stop, Kona drove a total of 27 + 27 = 54 miles. With the bakery stop, Kona drives an additional 60 - 54 = 6 miles. The answer is 6.
