Answer this question: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?
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 this question:There are 350 trees in the park, 70% of which are pine trees. How many are not pine trees?
There are 350 x 70 / 100 = 245 pine trees. Therefore, 350 - 245 = 105 trees are not pine trees.
The answer is 105.

Answer this question:An apartment complex has 4 identical buildings. Each building has 10 studio apartments, 20 2 person apartments, and 5 4 person apartments. How many people live in the apartment complex if it has 75% of its maximum occupancy?
First, we find out how many people live in each building. In addition to 10 1 person apartments, as a studio apartment is for a single person, there are 20 2 person apartments meaning there are 20 * 2 = 40 people capable of living there. We then find out how many people can live in the 4 person apartments by multiplying the number of available 4 person apartments by 4, performing 5 * 4 = 20 people capable of living there. So, in 1 building there is room for 10 + 40 + 20 = 70 people. We multiply this by the 4 buildings in total, finding a maximum occupancy of 4 * 70 = 280 people. We then multiply this by .75 to find out how many people would live there at 75% of maximum occupancy, performing 280 * .75 = 210 people.
The answer is 210.
