[Question]Mark has a garden with flowers. He planted plants of three different colors in it. Ten of them are yellow, and there are 80% more of those in purple. There are only 25% as many green flowers as there are yellow and purple flowers. How many flowers does Mark have in his garden?
[Answer]There are 80 / 100 * 10 = 8 more purple flowers than yellow flowers. So in Mark's garden, there are 10 + 8 = 18 purple flowers. Purple and yellow flowers sum up to 10 + 18 = 28 flowers. That means in Mark's garden there are 25 / 100 * 28 = 7 green flowers. So in total Mark has 28 + 7 = 35 plants in his garden. The answer is 35.
Q: Gretchen is a scuba diver. She likes to hunt for treasure on the ocean's floor, but when she finds something to keep, she must carry it back to the surface of the water to give it to her shipmate on the boat. She can only carry 3 objects at a time while she swims underwater. If she finds 17 objects underwater, what is the fewest number of trips to the surface of the water she must take to carry all 17 objects to the boat?
A: To carry 17 objects, three at a time, it takes 17 / 3 = 5 and 2 / 3 loads. This calculation means that she takes 5 trips carrying 3 objects per trip, and then she takes one additional trip carrying only two objects. Thus, in reality, she takes 5 + 1 = 6 trips to the surface. The answer is 6.
Question: Gail has some bills in her wallet which amount to $100. She has four $5 bills and three $20 bills, and the rest are $10 bills. How many $10 bills are in her wallet?
Answer: Four $5 bills amount to $5 x 4 = $20. Three $20 bills amount to $20 x 3 = $60. So Gail's $5 and $20 bills amount to $20 + $60 = $80. Thus, her $10 bills amount to $100 - $80 = $20. Therefore, she has $20 / $10 = 2 $10 bills. The answer is 2.
[Question]Lady Bird uses 1 1/4 cup flour to make 9 biscuits. She’s hosting this month's Junior League club which has 18 members and wants to make sure she allows 2 biscuits per guest. How many cups of flour will Lady Bird need?
[Answer]There will be 18 members and she wants to allow 2 biscuits per member so that’s 18 * 2 = 36 biscuits. Her biscuit recipe yields 9 biscuits and she needs to make 36 biscuits so she needs to make 36 / 9 = 4 batches of biscuits. 1 batch of biscuits uses 1 1 / 4 cup flour and she needs to make 4 batches so she will use 1.25 * 4 = 5 cups of flour. The answer is 5.
[Question]Jerry mows 8 acres of lawn each week. He mows ¾ of it with a riding mower that can cut 2 acres an hour. He mows the rest with a push mower that can cut 1 acre an hour. How long does Jerry mow each week?
[Answer]
Jerry mows 8 acres x ¾ = 6 acres with a riding mower. It will take him 6 acres / 2 each hour = 3 hours. Jerry mows 8 acres – 6 acres mowed with a riding mower = 2 acres with a push mower. It will take him 2 acres x 1 hour = 2 hours. It takes Jerry a total of 3 hours on the riding mower + 2 hours on the push mower = 5 hours. The answer is 5.
