Q: Haleigh decides that instead of throwing away old candles, she can use the last bit of wax combined together to make new candles. Each candle has 10% of it's original wax left. How many 5 ounce candles can she make if she has five 20 oz candles, 5 five ounce candles, and twenty-five one ounce candles?
A: She gets 2 ounces of wax from a 20 ounce candle because 20 x .1 = 2. She gets 10 ounces total from these candles because 5 x 2 = 10. She gets .5 ounces of wax from each five ounce candle because 5 x .1 = .5. She gets 1.5 ounces total from these candles because 5 x .5 = 2.5. She gets .1 ounces from each one ounce candle because 1 x .1 = .1. She gets 2.5 ounces from these candles because 25 x .1 = 2.5. She gets 15 ounces total because 10 + 2.5 + 2.5 = 15. She can make 3 candles because 15 / 5 = 3. The answer is 3.
Question: Barbie and Bruno have a pile of 144 coconuts that they need to move from one side of their yard to the other side. Barbie can carry 4 coconuts at a time, while Bruno can carry 8 coconuts at a time. If they make trips together carrying their maximum number of coconuts each time, how many trips together would they need to make to move all of the coconuts?
Answer: Together, they would carry a combined total of 4 + 8 = 12 coconuts per trip. To move 144 coconuts, they would need to make 144 / 12 = 12 trips. The answer is 12.
[Question]John buys 3 different coolers. The first one is 100 liters. The second is 50% bigger than that and the third is half the size of the second. How much total water can they hold?
[Answer]The second cooler is 100 * .5 = 50 liters bigger than the first. So it is 100 + 50 = 150 liters. The third is 150 / 2 = 75 liters. So the total water they can hold is 100 + 150 + 75 = 325 liters. The answer is 325.
Q: John has just turned 39. 3 years ago, he was twice as old as James will be in 6 years. If James' older brother is 4 years older than James, how old is James' older brother?
A: John was 39 - 3 = 36 years old 3 years ago. So that means in 6 years James will be 36 / 2 = 18 years old. So right now James is 18 - 6 = 12 years old. So James's older brother is 12 + 4 = 16 years old. The answer is 16.
Question: Nathan wants to line the inside of a box with velvet. The box has two long sides that measure 8 inches by 6 inches, two short sides that measure 5 inches by six inches and a top and a bottom that each measure 40 square inches. How many square inches of velvet does Nathan need?
Answer: First find the area of each long side by multiplying the length and width: 8 inches * 6 inches = 48 square inches. Then do the same thing for each short side: 5 inches * 6 inches = 30 square inches. Now add the area of one long side, one short side, and one top / bottom together: 48 square inches + 30 square inches + 40 square inches = 118 square inches. Now double that quantity because there are two of each kind of side: 118 square inches * 2 = 236 square inches. The answer is 236.
