Q: Dani has 3 cats; Binkie, Frankie and Spaatz. Each cat has a collar decorated with gemstones. Binkie has four times as many gemstones on his collar as does Frankie but Spaatz has two less than half as many gemstones on her collar as does Frankie. If Spaatz has 1 Gemstone on her collar, how many gemstones does Binkie have on his collar?
A: If Spaatz has 2 less than half the number of gemstones as does Frankie, then half as many as Frankie is 1 + 2 = 3 gemstones. If 3 is half the number of gemstones on Frankie's collar, then Frankie has 3 * 2 = 6 gemstones. If Binkie has 4 times as many gemstones as Frankie, then Binkie has 4 * 6 = 24. The answer is 24.
Question: For a class fundraiser, 30 students were asked to bring in 12 brownies each. 20 students were asked to bring in 24 cookies each and 15 students were asked to bring in 12 donuts each. If they sell everything for $2.00 each, how much money will they raise?
Answer: 30 students were asked to bring in 12 brownies so they will bring in 30 * 12 = 360 brownies. 20 students were asked to bring in 24 cookies each so that's 20 * 24 = 480 cookies. 15 students were asked to bring in 12 donuts each so that's 15 * 12 = 180 donuts. Together, they have 360 + 480 + 180 = 1,020 treats. If they sell all the treats for $2.00 each then they will make 1020 * 2 = $2,040.00. The answer is 2040.
[Question]A 25 story building has 4 apartments on each floor. If each apartment houses two people, how many people does the building house?
[Answer]If each building floor has 4 apartments, we have 25 floors * 4 apartments / floor = 100 apartments. If each apartment has 2 people, 100 apartments * 2 people / apartment = 200 people. The answer is 200.
Q: Haman's father has an egg business supplying the local market. On a Wednesday morning, his father sends him to go and collect 10 trays of eggs for sale from their store. While loading the eggs into the car, he accidentally drops two trays. He calls his father telling him this, and is told to add 7 more trays for sale. How many eggs were sold that day?
A: When Haman collected 10 trays and dropped 2 trays, he was left with 10 trays - 2 trays = 8 trays. When he added 7 more trays, the total number of trays became 8 trays + 7 trays = 15 trays. Since each tray contains 36 eggs, the total number of eggs to be sold is 36 eggs / tray * 15 trays = 540 eggs. The answer is 540.
Question: Jolene and Phil have four children, each with the same birthday. They gave birth to their first child exactly 15 years ago. They gave birth to their second child exactly one year after the birth of their first child. They gave birth to their third child on the fourth birthday of their second child. Two years after the birth of their third child, they gave birth to their fourth child. How old, in years, is their fourth child?
Answer:
Their 1st child was born 15 years ago, and therefore is 15 years old. Their 2nd child was born 1 year after their 15 - year - old child, and therefore is 15 - 1 = 14 years old. Their 3rd child was born 4 years after their 14 - year - old child, and therefore is 14 - 4 = 10 years old. Their 4th child was born 2 years after their 10 - year - old child, and therefore is 10 - 2 = 8 years old. The answer is 8.
