[Question]: Cassidy collects movie posters from newly released sci-fi movies. After this summer, she will have six more posters in her collection, making it double the size it was two years ago when she had 14 posters. How many posters does she have now?
[Answer]: Let C be the number of posters Cassidy has now. After this summer, she will have twice as many posters as when she had 14, so she will have C + 6 = 2 * 14 = 28 posters. Thus, Cassidy has C = 28 - 6 = 22 posters now.
So the answer is 22.

[Question]: Mark has to wait 4 days for his first coronavirus vaccine appointment. Then he has to wait 20 days for his second vaccine appointment. Then he has to wait 2 weeks for the vaccine to be fully effective. How many days does Mark have to wait in total?
[Answer]: 2 weeks have 2 weeks * 7 days per week = 14 days. Counting the days until the first and second vaccine, and the days to the vaccine to be fully effective, Mark has to wait 4 days + 20 days + 14 days = 38 days.
So the answer is 38.

[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.
