[Question]The government gives the bottom 20% of people a $2000 stimulus. They have found that this kind of stimulus returns 5 times as much money to the government, in terms of tax revenue, as it cost. The city has 1000 people in it. What was the government profit from this project?
[Answer]They gave money to 1000 * .2 = 200 people. It cost 200 * 2000 = $400,000. There was a 5 to 1 return so the government collected 5 * 400000 = $2,000,000. That means the profit was 2,000,000 - 400,000 = $1,600,000. The answer is 1600000.
Q: After a trip, Mrs. Nalani took the students to the restaurant and told them they could order either a burger or a hot dog. If the number of students who ordered burgers was 30, twice the number of students who called for a hot dog, calculate the number of students at the restaurant.
A: If the 30 students who ordered burgers were twice the number of students who ordered hot dogs, then 30 / 2 = 15 students ordered hot dogs. The total number of students is 15 + 30 = 45. The answer is 45.
Question: 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?
Answer: 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]James gets 3 parking tickets. The first 2 cost $150 each and the third cost 1/3 as much as one of these. His roommate agrees to pay half the cost. How much money does he have left if he had $500 in the bank?
[Answer]The third ticket cost $150 / 3 = $50. So the tickets cost $150 * 2 + $50 = $350. That means he paid $350 / 2 = $175. So he had $500 - $175 = $325 left over. The answer is 325.
Q: Ravi can jump higher than anyone in the class. In fact, he can jump 1.5 times higher than the average jump of the three next highest jumpers. If the three next highest jumpers can jump 23 inches, 27 inches, and 28 inches, how high can Ravi jump?
A: The total height the next three highest can jump is 78 inches because 23 + 27 + 28 = 78. The average height they can jump is 26 inches because 78 / 3 = 26. Ravi can jump 39 inches high because 26 x 1.5 = 39. The answer is 39.
