Q: Billy can spit a watermelon seed 30 inches. Madison can spit a watermelon seed 20% farther than Billy. Ryan can spit a watermelon seed 50% shorter than Madison. How far can Ryan spit a watermelon seed?
A: Madison can spit a seed 20% farther than Billy's 30 inches so that's .20 * 30 = 6 inches farther. Billy spits a seed 30 inches and Madison can spit 6 inches farther for a total of 30 + 6 = 36 inches. Ryan can spit a seed 50% shorter than Madison's 36 inches for a total of .50 * 36 = 18 inches. The answer is 18.
Question: There are 24 toys in the box and ¼ of them are action figures. The remaining toys are all dolls. How many dolls are there?
Answer: Since there are 24 toys in the box, there are ¼ * 24 = 6 action figures. Because the rest of the toys are dolls, there are 24 - 6 = 18 dolls in the box. The answer is 18.
[Question]John adopts a dog from a shelter. The dog ends up having health problems and this requires 3 vet appointments, which cost $400 each. After the first appointment, John paid $100 for pet insurance that covers 80% of the subsequent visits. How much did he pay in total?
[Answer]He got a discount of 400 * .8 = $320. He got that discount for 3 - 1 = 2 visits. So each of those visits cost 400 - 320 = $80. So he paid 2 * 80 = $160 for those visits. That means he paid a total of 400 + 160 + 100 = $660. The answer is 660.
Q: A floral shop had a three day sale on rose bouquets. On Monday, they sold 12 bouquets. On Tuesday, they sold three times that many bouquets. On Wednesday it rained all day and they only sold a third of what they did the day before. How many bouquets did they sell during the three day sale?
A: On Tuesday they sold 12 * 3 = 36 bouquets. On Wednesday they only sold 36 / 3 = 12 bouquets. In total they sold 12 + 36 + 12 = 60 bouquets. The answer is 60.
Question: Miles is a musician. He owns three fewer trumpets than he has fingers, and two more guitars than he has hands. He also owns two more trombones than he has heads, and one fewer French horn than he has guitars. What is the total number of musical instruments that Miles owns?
Answer: Three fewer trumpets than Miles has fingers is 10 - 3 = 7 trumpets. Two more guitars than he has hands is 2 + 2 = 4 guitars. Two more trombones than he has heads is 2 + 1 = 3 trombones. And one fewer French horn than he has guitars is 4 - 1 = 3 French horns. Altogether, Miles owns 7 + 4 + 3 + 3 = 17 musical instruments. The answer is 17.
Q: It takes 15 mink skins to make a coat. Andy buys 30 minks and each mink has 6 babies, but half the total minks are set free by activists. How many coats can he make?
A:
First find the total number of baby minks: 30 minks * 6 babies / mink = 180 minks. Add this to the number of adult minks: 180 minks + 30 minks = 210 minks. Then divide this number in half to find how many aren't set free: 210 minks / 2 = 105 minks. Then divide the remaining number of minks by the number of minks per coat to find the number of coats: 105 minks / 15 minks / coat = 7 coats. The answer is 7.
