Q: Parker wants to find out what the average percentage of kernels that pop in a bag is. In the first bag he makes, 60 kernels pop and the bag has 75 kernels. In the second bag, 42 kernels pop and there are 50 in the bag. In the final bag, 82 kernels pop and the bag has 100 kernels.
A: In the first bag the proportion that pops is .8 because 60 / 75 = .8. In the second bag the proportion that pops is .84 because 42 / 50 = .84. In the third bag the proportion that pops is .82 because 82 / 100 = .82. The proportions totals 2.46 because .8 + . 84 + .82 = 2.46. The average proportion is .82 because 2.46 / 3 = .82. The average percentage is 82 because .82 x 100 = 82. The answer is 82.
Question: Adonis is playing a prank on his dad by replacing his shampoo with hot sauce. Every day, after his dad showers, Adonis replaces the shampoo with 1/2 an ounce of hot sauce. He knows his dad uses 1 oz of shampoo a day from a new 10 oz bottle that no one else uses. After 4 days, what percentage of the liquid in the bottle is hot sauce?
Answer: Each day, the shampoo bottle goes down 1 / 2 an ounce because 1 - (1 / 2) = 1 / 2. After four days the shampoo bottle is 2 ounces lower because 4 x (1 / 2) = 2. After four days, the shampoo bottle has 8 ounces of liquid left because 10 - 2 = 8. After four days the shampoo bottle has 2 ounces of hot sauce 4 x (1 / 2) = 2. The proportion of hot sauce in the bottle is .25 because 2 / 8 = .25. The percentage of hot sauce is 25% because .25 x 100 = 25. The answer is 25.
[Question]Five coworkers were talking during the lunch break. Roger, the oldest one, said that he has the same amount of experience in years as all four of the others combined and that his retirement should come when he accumulates 50 years of experience. Peter said that when he came to the company his daughter was 7 years old, and now she is 19 years old. Tom then said he has twice as many years of experience as Robert. Robert said that he has 4 years of experience less than Peter but 2 more years of experience than Mike. How many more years does Roger have to work before he retires?
[Answer]Peter has 19 – 7 = 12 years of experience. Robert has 12 – 4 = 8 years of experience. Mike has 8 – 2 = 6 years of experience. Tom has 2 * 8 = 16 years of experience. Roger has 12 + 8 + 6 + 16 = 42 years of experience. Roger has to work another 50 – 42 = 8 years before he retires. The answer is 8.
[Question]Billy can spit a watermelon seed 30 inches. Madison can spit a watermelon seed 20% farther than Billy. Ryan can spit a watermelon seed 50% shorter than Madison. How far can Ryan spit a watermelon seed?
[Answer]
Madison can spit a seed 20% farther than Billy's 30 inches so that's .20 * 30 = 6 inches farther. Billy spits a seed 30 inches and Madison can spit 6 inches farther for a total of 30 + 6 = 36 inches. Ryan can spit a seed 50% shorter than Madison's 36 inches for a total of .50 * 36 = 18 inches. The answer is 18.
