[Question]If one Burmese python can eat one 50-cm alligator per week, how many Burmese pythons would it take to eat fifteen 50-centimeter alligators in three weeks?
[Answer]15 alligators eaten over a period of 3 weeks is a rate of 15 / 3 = 5 alligators per week. Under the normal rate of 1 alligator per week per python, it would take 5 / 1 = 5 pythons to eat 15 alligators in 3 weeks. The answer is 5.
Q: Amanda is figuring out how many bags of grass seed she needs to buy to cover a new lot the city is turning into a park. The lot measures 120 feet by 60 feet. One section that measures 40 feet by 40 feet will be covered with concrete, and the rest needs to be covered in grass seeds. Each bag of grass seeds covers 56 square feet. How many bags of grass seeds does Amanda need?
A: First find the area of the lot by multiplying the width and the length: 120 ft * 60 ft = 7200 sq ft. Then find the area of the square covered in concrete: 40 ft * 40 ft = 1600 sq ft. Then subtract the concrete area from the total area to find the grassy area: 7200 sq ft - 1600 sq ft = 5600 sq ft. Finally, divide this area by the area each bag covers to find the number of bags: 5600 sq ft / 56 sq ft / bag = 100 bags. The answer is 100.

[Answer]Labor cost is .5 * 60 = 30 dollars per hour. The cost for parts is 20 * 2 = $40. The total cost for labor is 220 - 40 = $180. He spent 180 / 30 = 6 hours on labor. The answer is 6.
Q: A nail salon was completely booked at 2 pm for manicures. Each manicure costs $20.00 per client so the salon made $200.00. If there are 210 fingers in the salon at 2 pm, and everyone has 10 fingers, how many people in the salon are not clients?
A: The salon made $200.00 and they charge $20.00 per client so there are 200 / 20 = 10 clients in the salon. There are 210 fingers in the salon and everyone has 10 fingers so there are 210 / 10 = 21 people in the salon. If there are 21 people in the salon and 10 are clients then there are 21 - 10 = 11 people in the salon that are not clients. The answer is 11.
