Q: 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?
A: 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.
Question: A school is planning a community outreach program. Each classroom must raise $200 for this activity. Classroom A has raised $20 from each of two families, $10 from each of eight families, and $5 from each of ten families. How much more money does Classroom A need in order to reach the goal?
Answer: Classroom A raised 2 x $20 = $40 from two families. They raised 8 x $10 = $80 from eight families. They raised 10 x $5 = $50 from ten families. Altogether, they raised $40 + $80 + $50 = $170. Therefore, they need $200 - $170 = $30 more to reach the goal. The answer is 30.
[Question]Peter has to walk 2.5 miles to get to the grocery store. If it takes him 20 minutes to walk one mile and he has walked 1 mile already, how many more minutes does he have to walk to reach it?
[Answer]Peter has to walk a remaining 2.5 total miles - 1 mile completed = 1.5 miles remaining. It will take him another 20 minutes * 1.5 miles remaining = 30 minutes to get to the grocery store. The answer is 30.
Q: Martha gets prize points every time she shops at her local grocery store. She gets 50 points per $10 spent, plus a 250 point bonus if she spends more than $100. Martha buys 3 pounds of beef for $11 each, 8 pounds of fruits and vegetables for $4/pound, 3 jars of spices for $6 each, and other groceries totaling $37. How many points does Martha get?
A: First find the total cost of the beef: $11 / pound * 3 pounds = $33. Then find the total cost of the fruits and vegetables: $4 / pound * 8 pounds = $32. Then find the total cost of the spices: $6 / jar * 3 jars = $18. Now add the cost of all the items to find Martha's total spending: $33 + $32 + $18 + $37 = $120. Now divide 50 points by $10 to find now many points Martha gets per dollar: 50 points / $10 = 5 points / dollar. Now multiply this exchange rate by Martha's total spending to find how many points she gets before the bonus: $120 * 5 points / dollar = 600 points. Finally, add the 250 point bonus Martha gets for spending more than $100: 600 points + 250 points = 850 points. The answer is 850.
Question: On Monday a group of 7 children and 5 adults went to the zoo. On Tuesday a group of 4 children and 2 adults went as well. Child tickets cost $3, and adult tickets cost $4. How much money did the zoo make in total for both days?
Answer:
The total amount of children that went on both days is 7 + 4 = 11. The cost of the children's tickets is 11 × $3 = $33. The total amount of adults that went on both days is 5 + 2 = 7. The cost of the adults' tickets is 7 × $4 = $28. The zoo made $33 + $28 = $61 in total. The answer is 61.
