Equilibrium price: Equilibrium price is the market price determined by the interaction between the quantity demanded and the quantity supplied.
Equilibrium quantity: Equilibrium quantity is the point where the quantity demanded is equal to the quantity supplied.
Demand: Demand refers to the total value of the goods and services that are demanded at a particular price in a given period of time.
Supply: Supply refers to the total value of the goods and services available for purchase at a particular price in a given period of time.
(b)
Identify the changes in equilibrium price and equilibrium quantity.

Explanation of Solution
If the demand falls and supply is constant, the equilibrium price and equilibrium quantity would decrease. The decrease in demand shifts the demand curve leftward, which leads to shift the equilibrium point. At the new equilibrium point, the price level and quantity demanded are lesser.

- Test Preparation QUESTION 2 [20] 2.1 Body Mass Index (BMI) is a summary measure of relative health. It is calculated by dividing an individual's weight (in kilograms) by the square of their height (in meters). A small sample was drawn from the population of UWC students to determine the effect of exercise on BMI score. Given the following table, find the constant and slope parameters of the sample regression function of BMI = f(Weekly exercise hours). Interpret the two estimated parameter values.

After the reopening of borders with mainland China following the COVID-19 lockdown, residents living near the border now have the option to shop for food on either side. In Hong Kong, the cost of food is at its listed price, while across the border in mainland China, the price is only half that of Hong Kong's. A recent report indicates a decline in food sales in Hong Kong post-reopening. ** Diagrams need not be to scale; Focus on accurately representing the relevant concepts and relationships rather than the exact proportions. (a) Using a diagram, explain why Hong Kong's food sales might have dropped after the border reopening. Assume that consumers are indifferent between purchasing food in Hong Kong or mainland China, and therefore, their indifference curves have a slope of one like below. Additionally, consider that there are no transport costs and the daily food budget for consumers is identical whether they shop in Hong Kong or mainland China.
