[Question]A department store offers a 10% discount for the amount exceeding $100 of the customer's total charge. Jaco bought a pair of shoes for $74; 2 pairs of socks that cost $2 per pair; a bag that costs $42. How much will Jaco pay for those items?
[Answer]Two pairs of socks cost $2 x 2 = $4. Jaco's total charge is $74 + $4 + $42 = $120. The amount that exceeds $100 is $120 - $100 = $20. So, Jaco has $20 x 10 / 100 = $2 discount. Therefore, Jaco will pay $120 - $2 = $118 for those items. The answer is 118.
Q: Heisenberg owns a pharmacy. He earned a total of $80 from 100 mg amoxicillin and $60 from 500 mg amoxicillin every week. If each capsule of 100 mg amoxicillin costs $5 and each capsule of 500 mg amoxicillin costs $2, how many capsules of amoxicillin does he sell every 2 weeks?
A: Heisenberg sells a total of $80 / 5 = 16 capsules of 100 mg amoxicillin every week. So, the total number of 100 mg amoxicillin he sells every 2 weeks is 16 x 2 = 32. And he sells $60 / 2 = 30 capsules of 500 mg amoxicillin every week. So, the total number of 500 mg amoxicillin he sells every 2 weeks is 30 x 2 = 60. Therefore, the total number of capsules he sells every 2 weeks is 60 + 32 = 92. The answer is 92.
Question: Zoe made a total of $8,000 cleaning pools and babysitting. She babysat Julie three times as often as she babysat Zachary. The number of times she babysat Zachary was 1/5 the number of times she babysat Chloe. If Zoe made $600 babysitting Zachary, how much did she earn from pool cleaning?
Answer: From babysitting Julie, Zoe made 3 * 600 = 1800 dollars, since she made $600 babysitting Zachary and she babysat Julie three times as often. Since she babysat Zachary 1 / 5 as often as she babysat Chloe, she made an additional 5 * 600 = 3000 dollars from babysitting Chloe. All together, the babysitting sessions made Zoe 600 + 1800 + 3000 = 5400 dollars. Subtracting babysitting payments from the total gives 8000 - 5400 = 2600 dollars. Zoe therefore made 2600 dollars cleaning pools. The answer is 2600.
[Question]At the aquarium, there are twice as many sharks as stingrays. If there are 28 stingrays, how many fish are there?
[Answer]If sharks are twice the number of stingrays, then the number of sharks at the aquarium is 2 sharks / stingray * 28 stingrays = 56 sharks. The number of fish in the tank is 56 sharks + 28 stingrays = 84 fish. The answer is 84.
Q: Pat is having a picnic with her family. She has 42 cookies. She also has 63 pieces of candy and 21 brownies. There are 7 people in her family. If each person gets the same number of each dessert, how much will each person get?
A: Each person gets 42 cookies / 7 people = 6 cookies. Each person gets 63 pieces of candy / 7 people = 9 pieces of candy. Each person gets 21 brownies / 7 people = 3 brownies. Each person will get 6 + 9 + 3 = 18 desserts. The answer is 18.
Question: Susan had a sum of money. She spent 1/5 of it in September, 1/4 of it in October, and $120 in November. After spending these amounts of money, she still had $540 left. How much money did she have at first?
Answer:
Let X be the amount Susan had originally. Susan spent 1 / 5 * X in September, 1 / 4 * X in October, and $120 in November. Susan has X - 1 / 5 * X - 1 / 4 * X - $120 = $540 left. Combining like terms, we get 11 / 20 * X - $120 = $540. Adding $120 to both sides, we get 11 / 20 * X = $660. Dividing both sides by 11 / 20 we get X = $1200. The answer is 1200.
