Kindly help me please with these questions on the aggregate model of the macro economy.

in my opinion, cheerios aren't a necessity especially after a devastating natural disaster such as a hurricane, however, due to disruption in roads, maybe the price will increase due to scarcity of transportation.

1) To predict which prices rose after Hurricane Sandy in the USA, all we need to do is look at businesses facing large shifts in either their demand or supply curves after the storm.

The hotel industry saw a large outward shift of the demand curve in its market. Higher prices and price gouging became possible.

Gas prices rose after Sandy as supply shifted to the left, or inward, given transport problems. Transport problems likely also affected the delivery of Cheerios. Do you expect the price of Cheerios to also rise substantially? Why or why not?

2) Every summer, New York City puts on free performances of Shakespeare in the Park.The true cost of a ticket is $0 plus the opportunity cost of the time spent in line.Students can produce tickets relatively cheaply by waiting in line. They can then turn around and sell those tickets to high-wage Shakespeare lovers.Many museums offer free admission one day a week, on a weekday. On that day we observe that museumgoers are more likely to be senior citizens than on a typical Saturday. Why?

my opinion;Is it maybe because they appreciate the relics more than the modernalized plays.plus also maybe because in the park there are plenty of distractions?

3)During the gasoline shortage in 1974 some students started an interesting business. These entrepreneurial students observed that the opportunity cost of waiting in line to buy gasoline was very high for many people. But there was another group - students - for whom the opportunity cost of time was considerably lower. These entrepreneurs hired their fellow students, then rented their services to wait in gasoline lines, allowing the car owner to make better use of their time. In addition the students could make use of that time for studying.

An entrepreneurial gasoline station owner told prospective customers they could buy as much gasoline as they wanted. But they first had to buy a stuffed teddy bear from him. The price of the bear was $25. (Federal regulators told him to cut it out.)

Explain two ways in which these business activities improved overall economic welfare.
