[Question]Jenny has a tummy ache. Her brother Mike says that it is because Jenny ate 5 more than thrice the number of chocolate squares that he ate. If Mike ate 20 chocolate squares, how many did Jenny eat?
[Answer]Thrice the number of chocolate squares that Mike ate is 20 squares * 3 = 60 squares. Jenny therefore ate 60 squares + 5 squares = 65 chocolate squares. The answer is 65.
Q: Ivan has a bird feeder in his yard that holds two cups of birdseed. Every week, he has to refill the emptied feeder. Each cup of birdseed can feed fourteen birds, but Ivan is constantly chasing away a hungry squirrel that steals half a cup of birdseed from the feeder every week. How many birds does Ivan's bird feeder feed weekly?
A: The squirrel steals 1 / 2 cup of birdseed every week, so the birds eat 2 - 1 / 2 = 1 1 / 2 cups of birdseed. Each cup feeds 14 birds, so Ivan's bird feeder feeds 14 * 1 1 / 2 = 21 birds weekly. The answer is 21.
Question: Lisa is looking to attempt a World Record. She has decided to try and match Joey Chestnut's record of eating 75 full hotdogs, buns included, in 10 minutes. Halfway through the time Lisa has eaten 20 hotdogs. How many hotdogs will she have to eat per minute to at least tie Joey Chestnut's record?
Answer: Joey Chestnut ate 75 hotdogs to claim the record and Lisa has eaten 20 hot dogs so far, so she still needs to eat 75 - 20 = 55 hotdogs to tie Joey Chestnut. Lisa has a 10 minute time period to eat the hotdogs and half the time has already passed, which means Lisa has 10 / 2 = 5 minutes left until the competition is over. If she needs to eat 55 hotdogs to tie Joey Chestnut and there are 5 minutes left in the competition period then she needs to eat 55 / 5 = 11 hot dogs per minute to have a chance of tying for a win. The answer is 11.
[Question]While cultivating a small farm, a farmer spent $50 on corn seeds, $35 on fertilizers and pesticides, and $15 on labor. After a successful harvest, he was able to gather 10 bags of corn. How much should he sell each bag, if he wants to make a profit of 10%?
[Answer]His total expenditure so far is $50 + $35 + $15 = $100. To make a profit of 10%, he has to make a total of $100 + ($100 * (10 / 100) = $110 from sales. To make $110 from the sales of 10 bags, each bag should cost $110 / 10 = $11. The answer is 11.
Q: A portable computer drive has enough kilobytes of storage space to store 2000 photos. Each photo is 1.5 kilobytes in size. How many 200-kilobyte videos can it store if it already has 400 photos on it?
A: The drive has 1.5 * 2000 = 3000 kilobytes of storage space. It already has 1.5 * 400 = 600 kilobytes of storage space taken up. Thus, it has 3000 - 600 = 2400 kilobytes of space left. The portable drive can store 2400 / 200 = 12 200 - kilobyte videos on it with 400 photos. The answer is 12.
Question: Jerry is sweeping up pieces of broken glass in the parking lot. He sweeps up 20 amber pieces, 35 green pieces, and some clear pieces. If the green pieces are 25% of the total glass he sweeps up, how many pieces were clear?
Answer:
First find the total number of glass pieces Jerry sweeps up: 35 green pieces / .25 = 140 pieces. Then subtract the number of pieces of other colors: 140 pieces - 20 pieces - 35 pieces = 85 pieces. The answer is 85.
