- ***Just the last paragraph of the question please*** A ski resort in the White Mountains has conducted market and cost studies, and has determined that the demand and supply for ski-lift tickets at their resort are represented by: Qd=1750 - 5P - 8PR + 2PB; Qs=50 + 20P - 3PE. In these equations, P represents the price of a full-day lift ticket, in dollars per ticket; PR is the price of a ski-rental package; PB is the price of a pint of beer at the local pub in the nearby town; and PE is the price per megawatt hour for the electricity used to run the chair lifts on the ski slopes. Based on the equations above, determine whether the beer in the local pub is a substitute or complement to skiing. Briefly explain your answer. Suppose the price of a ski-rental package is $20, the price of a pint of beer is $5, and the price of electricity is $150 per megawatt hour.

The average monthly demand for onions in the country is around 17,000 metric tons but the current supply is not enough to meet the demand. This has resulted in a shift in the demand curve to the right and the supply curve to the left, causing the market equilibrium to move from point E to point F, resulting in an increase in both price and quantity. Reason of the shift: The price increase of onions in the Philippines can be attributed to several factors, including global inflation, failure of the agriculture department to make accurate supply projections, possible internal price manipulation, and a shortage of supply due to smuggling.arrow_forwardGraph Input Tool Market for Peacock's Hotel Rooms 500 450 I Price (Dollars per room) 350 400 Quantity Demanded (Hotel rooms per night) 150 350 300 250 Demand Factors 200 150 Average Income (Thousands of dollars) Demand 40 100 Airfare from JFK to LAS (Dollars per roundtrip) 50 + 200 50 100 150 200 250 300 350 400 450 500 Room Rate at Grandiose (Dollars per night) QUANTITY (Hotel rooms) 250 For each of the following scenarios, begin by assuming that all demand factors are set to their original values and Peacock is charging $350 per room per night.
