Question: Era had 5 burgers for her and her 4 friends. She sliced each burger into halves. The first and second friends got 1 and 2 slices, respectively. Then the third and fourth friends got 3 slices each. How many slices of burgers are left for Era?
Answer: There are 5 x 1 / 2 = 10 halves of burgers made from 5 whole burgers. Era's first and second friends got 1 + 2 = 3 slices together. Her third and fourth friends got 3 + 3 = 6 slices together. Era's four friends got 3 + 6 = 9 slices. So, Era is left with 10 - 9 = 1 slice. The answer is 1.
[Question]A global gym decides to replace all of its cardio machines. They have 20 gyms. Each gym has 10 bikes, 5 treadmills, and 5 elliptical machines. The bikes cost $700 each. The treadmills cost 50% more than that. The elliptical machines are twice as expensive as the treadmills. How much does it cost to replace everything?
[Answer]The gym needs to buy 20 * 10 = 200 bikes. 20 * 5 = 100 each of treadmills and ellipticals. So the bikes cost 200 * 700 = $140,000. The treadmills cost 700 * 1.5 = $1,050 each. So they cost a total of 1050 * 100 = $105,000. The ellipticals each cost 1050 * 2 = $2100. So in total the ellipticals cost 2100 * 100 = $210,000. So the total cost of everything is 140,000 + 105,000 + 210,000 = $455,000. The answer is 455000.
Q: Alex has not washed his clothes for a month; 18 shirts, 12 pants, 17 sweaters, and 13 jeans are waiting to be washed. Alex's washing machine can wash a maximum of 15 items per cycle. Each cycle takes 45 minutes. How many hours will it take the washing machine to wash all the clothes?
A: Alex will wash 18 + 12 + 17 + 13 = 60 items. With 20 items per wash cycle, Alex will wash the clothes in 60 / 15 = 4 cycles. With 45 minutes per cycle, the washing machine will take 45 * 4 = 180 minutes to wash the clothes. As 1 hour has 60 minutes, the washing machine will take 180 / 60 = 3 hours to wash the clothes. The answer is 3.
Question: 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?

[Question]Fabian went to a park to get some fresh air. He decided to walk there for 3 hours. Every hour he covers 5 kilometers. How many more hours did Fabian need to walk to reach a total of 30 kilometers?
[Answer]To walk 30 kilometers, Fabian would need to walk for 30 km / 5 km / hour = 6 hours. As he had already walked for 3 hours, he would need to walk for another 6 hours - 3 hours = 3 hours. The answer is 3.
[Question]The average score on last week's Spanish test was 90. Marco scored 10% less than the average test score and Margaret received 5 more points than Marco. What score did Margaret receive on her test?
[Answer]
The average test score was 90 and Marco scored 10% less so 90 * .10 = 9 points lower. The average test score was 90 and Marco scored 9 points less so his test score was 90 - 9 = 81. Margret received 5 more points than Marco whose test score was 81 so she made 5 + 81 = 86 on her test. The answer is 86.
