Question: Miss Molly surveyed her class of 30 students about their favorite color. Half of the class answered green, one-third of the girls answered pink, and the rest of the class answered yellow. If there are 18 girls in the class, how many students like yellow best?
Answer: 30 / 2 = 15 students answered green. 18 / 3 = 6 girls answered pink. So, 15 + 6 = 21 students answered either green or pink. Therefore, 30 - 21 = 9 answered yellow. The answer is 9.
[Question]An entrepreneur is crowdfunding a new business effort. He has three different dollar amount levels of financial backing options and each level is ten times as high as the previous one. He needs to raise $12000 to get his business off the ground. He succeeded after getting two backers at the highest level of financial backing, three at the second level, and ten at the lowest level. How many dollars was the highest level of financial backing?
[Answer]Let L represent the lowest level of financial backing. Thus, the second level is 10L and the highest level is 10 * 10L = 100L. The entrepreneur got 2 highest level backers, 3 second level backers, and 10 lowest level backers, so 2 * 100L + 3 * 10L + 10L = 200L + 30L + 10L = 240L = $12000. Therefore, the lowest level of financial backing was L = 12000 / 240 = $50. Thus, the highest level of financial backing was 10 * 10 * 50 = $5000. The answer is 5000.
Q: If Billy and Jenny each order a $20 steak along with a $5 drink, how much will Billy have to pay in tips if he wants to cover 80% of a 20% tip for the two of them?
A: First, we figure out the price per meal by adding the steak and the drink together, finding a cost of 20 + 5 = 25 per meal. Then we multiply this by 2, as there are two people eating, meaning a total cost of 25 * 2 = 50 for both meals. Then we find the total tip amount for a 20% tip, by multiplying 50 * .2 = 10. Then we find out what 80% of this tip amount is by multiplying the desired tip of 10 by .8, finding 10 * .8 = 8 dollars that Billy should contribute. The answer is 8.
Question: Lennon is a sales rep and is paid $0.36 in mileage reimbursement when he travels to meet with clients. On Monday he drove 18 miles. Tuesday he drove 26 miles. Wednesday and Thursday he drove 20 miles each day and on Friday he drove 16 miles. How much money will he be reimbursed?
Answer: In one week he drove 18 + 26 + 20 + 20 + 16 = 100 miles. He is reimbursed $0.36 per mile of travel, and he travels 100 miles so he will receive .36 * 100 = $36.00. The answer is 36.
[Question]Bella bought stamps at the post office. Some of the stamps had a snowflake design, some had a truck design, and some had a rose design. Bella bought 11 snowflake stamps. She bought 9 more truck stamps than snowflake stamps, and 13 fewer rose stamps than truck stamps. How many stamps did Bella buy in all?
[Answer]The number of truck stamps is 11 + 9 = 20. The number of rose stamps is 20 − 13 = 7. Bella bought 11 + 20 + 7 = 38 stamps in all. The answer is 38.

If each candle is 8 ounces of beeswax and 1 ounce of coconut oil, then each candle weighs 8 + 1 = 9 ounces. Three less than 10 candles is 10 - 3 = 7 candles. Thus, 7 candles, each weighing 9 ounces, will have a combined weight of 7 * 9 = 63 ounces. The answer is 63.
