Question: MIlle is making snack packs for her kindergarten class. She's going to divide 64 pretzels, four times as many goldfish, and 32 suckers into baggies for the 16 kids in the class. How many items does each baggie have?
Answer: First find the total number of goldfish Millie adds: 64 pretzels * 4 goldfish / pretzel = 256 goldfish. Then add the number of each kind of snack to find the total: 256 goldfish + 64 pretzels + 32 suckers = 352 snacks. Then divide the total number of snacks by the number of baggies to find the number of snacks per baggie: 352 snacks / 16 baggies = 22 snacks / baggie. The answer is 22.
[Question]Jonas is a book collector. He has so many books he is converting his third bedroom into a library. This room has 400 square feet of space. He plans to put several bookshelves in the room and each bookshelf takes up 80 square feet of space. If he reserves 160 square feet of space to use for a desk and some walking space, how many shelves can he put in the room?
[Answer]If he reserves 160 sq. ft. of space for a desk and some walking space, then he will have 400 - 160 = 240 sq. ft. of space remaining. If each bookshelf takes up 80 sq. ft. of space, then 240 sq ft can contain 240 / 80 = 3 bookshelves. The answer is 3.
Q: An entrepreneur is crowdfunding a new business effort. He has three different dollar amount levels of financial backing options and each level is ten times as high as the previous one. He needs to raise $12000 to get his business off the ground. He succeeded after getting two backers at the highest level of financial backing, three at the second level, and ten at the lowest level. How many dollars was the highest level of financial backing?
A: Let L represent the lowest level of financial backing. Thus, the second level is 10L and the highest level is 10 * 10L = 100L. The entrepreneur got 2 highest level backers, 3 second level backers, and 10 lowest level backers, so 2 * 100L + 3 * 10L + 10L = 200L + 30L + 10L = 240L = $12000. Therefore, the lowest level of financial backing was L = 12000 / 240 = $50. Thus, the highest level of financial backing was 10 * 10 * 50 = $5000. The answer is 5000.
Question: James was doing some shopping in his favorite shop and he saw an offer on shoes that give him a second pair of shoes for half off the original price. He took the offer and took the first pair of shoes for $40 and the second one for $60. At the cashier, the lady told him that the offer applies strictly to the cheaper pair of shoes, and also that he was selected for an extra discount of a fourth off the total amount. How much money did James end up paying for both pairs of shoes?
Answer:
The price of the cheaper pair after the discount was $40 / 2 = $20. The total price of both pairs of shoes $20 + $60 = $80. The final discount was $80 / 4 = $20. The price he ends up paying was $80 - $20 = $60. The answer is 60.
