Q: Bob, a marathon runner, is preparing for a race. He runs a total of 70 miles in the 3 days leading up to the race. On day one he runs 20 percent of the total miles and on day 2 he runs 50 percent of the remaining miles. How many miles does he run on day three to complete the 70 miles?
A: Day 1: 70(.20) = 14 miles. 70 - 14 = 56 miles remaining. Day 2:56 / 2 = 28 miles. 56 - 28 = 28 miles remaining. The answer is 28.

[Question]Three blue chips are in a jar which is 10% of the entire chips. If 50% of the chips are white and the rest are green, how many green chips are there?
[Answer]10% + 50% = 60% of the chips in the jar are not green. So, 100% - 60% = 40% of the chips are green. There are 40% / 10% = 4 sets of 10% to make 40%. Hence, there are 3 chips x 4 sets = 12 green chips. The answer is 12.
Q: Yesterday Ryan got five books from the library. They were a total of 2100 pages. His brother got one book a day that was 200 pages each. They both finished them in a week. On average, how many more pages per day did Ryan read compared to his brother?
A: Ryan read an average of 300 pages a day because 2100 / 7 = 300. He read 100 more pages a day on average than his brother because 300 - 200 = 100. The answer is 100.
Question: Two teams are playing in a stadium with a capacity of 2000 people. The total number of people in the stadium is 3/4 of the total capacity and each person paid $20 in entry fees. What is the difference between the total amount of fees collected when the stadium was 3/4 full and if the stadium would have been full?
Answer: When the stadium is full, the total fees charged is 2000 * $20 = $40000. When the stadium is 3 / 4 full, the total number of people in is 3 / 4 * 2000 = 1500 people. The total entry fees collected when the stadium is 3 / 4 full is 1500 * $20 = $30000. The difference in the total entry fees when the stadium is full and when it's 3 / 4 full is $40000 - $30000 = $10000. The answer is 10000.
Q: Jacque arrived in France and his suitcase weighed 5 pounds. While in France, he picked up 5 bottles of perfume that weighed 1.2 ounces each, 4 pounds of chocolate, 2 bars of soap that weighed 5 ounces each and 2 jars of jam that weighed 8 ounces each. Considering 16 ounces is the same as 1 pound, how much did Jacque's suitcase weigh on the return flight home?
A:
He bought 5 bottles of perfume that weighed 1.2 oz each so they weighed 5 * 1.2 = 6 oz. 2 bars of soap weighed 5 oz each so they weighed 2 * 5 = 10 oz. 2 jars of jam weighed 8 oz each so they weighed 2 * 8 = 16 oz. The perfume is 6 oz, the soap is 10 oz and the jam is 16 oz for a total of 6 + 10 + 16 = 32 oz. 16 oz is 1 pound, and he had 32 oz in products so he had 32 / 16 = 2 pounds of products. His suitcase weighed 5 pounds, and the chocolate weighed 4 pounds and the remaining products weighed 2 pounds so his suitcase weighed 5 + 4 + 2 = 11 pounds. The answer is 11.
