Answer: inelastic
Explanation:
If increasing the admission charge for National Parks increases the National Park Service's total revenue, then the demand for National Park visits is inelastic.

15,500,000/250,000 = 62

An increase in the price of coffee beans can be expected to increase the demand for pie.
So, in the market if the price of coffee beans increases, quantity demanded for coffee will decrease. As, the coffee in turn is a complement to pie the consumers using coffee will now shift themselves to pie, unless the price decreases for coffee. Thus, the demand for pie is expected to increase now.
Several events could lead to such a change, an increase in population , an increase in incomes, or an increase in the price likely to increase the quantity of coffee demanded at each price.
Hence, this represents the Law of Demand.
