Macy has a goal of running a total of 24 miles per week. If she runs 3 miles per day, how many miles does Macy have left to run after 6 days so that she could meet her goal? Give the rationale and then the answer.
Let's think step by step. In 6 days, Macy is able to run 3 x 6 = 18 miles. Therefore, she has 24 – 18 = 6 miles left to run to meet her goal.. The answer is: 6.

An online newspaper had listed 100 visitors in October. The number of visitors in November increased by 15%. There were 15 more visitors in December than in November. What is the total number of visitors for these three months? Give the rationale and then the answer.
Let's think step by step. There was an increase of 100 x 15 / 100 = 15 visitors in November. So, the number of visitors in November was 100 + 15 = 115. In December, the number of visitors was 115 + 15 = 130. Therefore, a total of 100 + 115 + 130 = 345 visitors listed in these three months.. The answer is: 345.

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. Give the rationale and then the answer.
Let's think step by step. 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.
