[Question]: The total mask production was doubled every month by a company after the outbreak of Coronavirus due to increased demand. If the company produced 3000 masks in March, calculate the total mask production of July.
[Answer]: If in March the company produced 3000 masks, in April, after doubling the total mask production, the company produced 3000 * 2 = 6000 masks. In May, the company doubled its total mask production to 2 * 6000 = 12000. After doubling the production for June, the company was able to produce 2 * 12000 = 24000. By July, the company was producing a total of 2 * 24000 = 48000 masks.
So the answer is 48000.

[Question]: To support the school outreach program, Einstein wants to raise $500 by selling snacks. One box of pizza sells for $12, a pack of potato fries sells for $0.30, and a can of soda at $2. Einstein sold 15 boxes of pizzas, 40 packs of potato fries, and 25 cans of soda. How much more money does Einstein need to raise to reach his goal?
[Answer]: Einstein collected 15 x $12 = $180 for selling pizzas. He collected 40 x $0.30 = $12 for the 40 packs of potato fries. He collected 25 x $2 = $50 for the 25 cans of soda. Thus, the total amount section Einstein collected was $180 + $12 + $50 = $242. Therefore, Einstein needs $500 - $242 = $258 more to reach the goal.
So the answer is 258.

[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?
[Answer]:
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.
So the answer is 100.
