Answer

Brief Explanations:

  • Question 22: Technological improvements increase production efficiency, shifting the supply curve to the right. In the graphs, a right - shift of the supply curve is shown in Graph A.
  • Question 23: An increase in the price of a key ingredient (tapioca flour) raises production costs. Higher costs lead to a decrease in supply.
  • Question 24: An increase in the price of key components to manufacture turntables raises production costs, causing the supply curve to shift to the left.
  • Question 25: At a price of $3, the quantity demanded is the sum of the quantities demanded by each consumer ($3 + 5+2=10$). According to the law of demand, when the price falls, the quantity demanded is likely to increase.

Answer:

  1. D. graph A
  2. A. The supply of bubble tea will decrease.
  3. A. an increase in the price of key components to manufacture turntables
  4. D. ten; increase
