Q: The math questions in a contest are divided into three rounds: easy, average, and hard. There are corresponding points given for each round. That is 2, 3, and 5 points for every correct answer in the easy, average, and hard rounds, respectively. Suppose Kim got 6 correct answers in the easy; 2 correct answers in the average; and 4 correct answers in the difficult round, what are her total points in the contest?
A: Kim got 6 points / round x 2 round = 12 points in the easy round. She got 2 points / round x 3 rounds = 6 points in the average round. She got 4 points / round x 5 rounds = 20 points in the difficult round. So her total points is 12 points + 6 points + 20 points = 38 points. The answer is 38.
Question: Lizzie has half as many crayons as Bobbie. Bobbie has three times as many crayons as Billie. If Billie has 18 crayons, how many crayons does Lizzie have?

[Question]John ends up damaging his hearing aids. He needs to replace both of them. They cost $2500 each. Insurance covers 80% of the cost. How much does he personally have to pay?
[Answer]The cost of the hearing aids is $2500 * 2 = $5000. So insurance covers $5000 * .8 = $4000. That means it cost him $5000 - $4000 = $1000. The answer is 1000.
Q: Pauline will make tacos for dinner. She bought a box of taco shells that cost $5, 4 bell peppers that cost $1.5 each, and 2 pounds of meat that cost $3 per pound. How much did she spend in all?
A: She spent 4 x $1.5 = $6 for the four bell peppers. She spent 2 x $3 = $6 for the 2 pounds of meat. So, Pauline spent $5 + $6 + $6 = $17 in all. The answer is 17.
Question: Jenny had $24 left after spending 3/7 of her money. How much is half of her original amount of money?
Answer: Jenny spent 1 - 3 / 7 = 4 / 7 of her money. Since 4 / 7 is equal to $24, then 1 / 7 is equal to $24 / 4 = $6. So, Jenny originally had $6 x 7 = $42. Therefore, half of her original amount of money is $42 / 2 = $21. The answer is 21.
Q: While passing by a store, Miley noticed that a bag that cost $150 last week is now on sale for $135. What percent is the discount?
A:
The bag is now sold for $150 - $135 = $15 less. The discount is 15 / 150 = 1 / 10. Thus, the percent discount is 1 / 10 x 100% = 10%. The answer is 10.
