Question: In a house, there are 16 cats. Two of them are white, and 25% of them are black. The rest of the cats are grey. How many grey cats are in this house?
Answer: In this house, there are 16 * 25 / 100 = 4 black cats. If there are two white cats, that means that there are 16 - 4 - 2 = 10 grey cats in this house. The answer is 10.
[Question]On Rudolph's car trip across town, he traveled 2 more than 5 miles and encountered 3 less than 17 stop signs. How many stop signs per mile did Rudolph encounter on his trip across town?
[Answer]He traveled 2 more than 5 miles, or 5 + 2 = 7 miles. He encountered 3 less than 17 stop signs, or 17 - 3 = 14 stop signs. Thus, during his trip across town, Rudolph encountered 14 / 7 = 2 stop signs per mile. The answer is 2.
Q: In the jar, there are 7 blue marbles, 11 red marbles, and some yellow marbles. If the chance of randomly picking a yellow marble is 1/4, how many yellow marbles are there?
A: Let y be the number of yellow marbles. There are 11 + 7 + y = 18 + y total marbles. y / (18 + y) = 1 / 4. 4y = 18 + y. 3y = 18. y = 6. There are 6 yellow marbles. The answer is 6.
Question: Rodney and Todd are rowing down a river that is 50 yards wide at one end. If the river's width increases from this end uniformly by 2 yards every 10 meters along, and they row along the river at a rate of 5 m/s, how long (in seconds) will it take them to get to the point where the river is 80 yards wide?
Answer: The difference in width between where they're starting from and their destination is 80 - 50 = 30 yards. The width increases 2 yards every 10 m along the river so they would have to cover (30 / 2) * 10 = 150 meters. Traveling at the rate of 5m / s, he will spend 150 / 5 = 30 seconds. The answer is 30.
[Question]Kalani has twenty candles in her bedroom, twice the number of candles in the living room. Donovan, her brother, brings in 20 more candles he bought from the candle shop. What's the total number of candles in the house?
[Answer]If the number of candles in the bedroom is twice the number in the living room, there are 20 / 2 = 10 candles in the living room. When Donovan brings in 20 more candles, the total number of candles becomes 10 + 20 + 20 = 50. The answer is 50.
[Question]Janet works as an exterminator and she also sells molten metal casts of fire ant nests on the Internet. Janet gets paid $70 an hour for exterminator work and makes $20/pound on her ant nest sculptures. If she does 20 hours of exterminator work and sells a 5-pound sculpture and a 7-pound sculpture, how much money does she make?
[Answer]
First find Janet's total earnings from the exterminator work: $70 / hour * 20 hours = $1400. Then find the total number of pounds of sculpture she sells: 5 pounds + 7 pounds = 12 pounds. Then find her total earnings from the sculptures: 12 pounds * $20 / pound = $240. Then add that amount to the amount she makes as an exterminator to find her total earnings: $240 + $1400 = $1640. The answer is 1640.
