Q6. On the production possibilities frontier shown, the opportunity cost to the economy of getting 30 additional toothbrushes by moving from point A to point D is

Background

Topic: Production Possibilities Frontier (PPF) and Opportunity Cost

This question tests your understanding of how to use a PPF graph to calculate the opportunity cost of shifting resources from producing one good to another.

Key Terms and Formulas

• Production Possibilities Frontier (PPF): A curve showing the maximum attainable combinations of two products that may be produced with available resources and technology.

• Opportunity Cost: The value of the next best alternative forgone when a choice is made.

• Formula:

Step-by-Step Guidance

1. Identify the coordinates for points A and D on the PPF. Note the quantities of toasters and toothbrushes at each point.

2. Calculate the change in toothbrushes (Good X) and the corresponding change in toasters (Good Y) as you move from A to D.

3. Apply the opportunity cost formula: divide the decrease in toasters by the increase in toothbrushes.

4. Set up the calculation, but do not compute the final value yet.

Q7. On the production possibilities frontier shown, the opportunity cost of getting 15 additional toasters by moving from point D to point C is

Background

Topic: Opportunity Cost on the PPF

This question asks you to calculate the opportunity cost of increasing the production of one good (toasters) by reducing the production of another (toothbrushes) using the PPF.

Key Terms and Formulas

• Opportunity Cost: The amount of one good that must be given up to obtain more of another good.

• Formula:

Step-by-Step Guidance

1. Find the coordinates for points D and C on the PPF. Record the quantities of toasters and toothbrushes at each point.

2. Determine the increase in toasters and the decrease in toothbrushes as you move from D to C.

3. Use the opportunity cost formula: divide the decrease in toothbrushes by the increase in toasters.

4. Set up the calculation for the opportunity cost, but do not solve for the final value yet.

Q10. According to the graph, the opportunity cost of 1 bushel of wheat for Cliff is

Background

Topic: Comparative Advantage and Opportunity Cost

This question tests your ability to read a PPF and calculate the opportunity cost of producing one good in terms of another for a specific producer.

Key Terms and Formulas

• Opportunity Cost: The amount of one good that must be given up to produce an additional unit of another good.

• Formula:

Step-by-Step Guidance

1. Look at Cliff's PPF and identify the maximum amount of wheat and corn he can produce.

2. Calculate how much corn Cliff gives up to produce one more bushel of wheat.

3. Set up the opportunity cost calculation using the formula above.

4. Write the ratio but do not simplify to the final value yet.

Q21. According to the graph shown, in this market, equilibrium price and quantity would be

Background

Topic: Market Equilibrium

This question tests your ability to find the equilibrium price and quantity where the supply and demand curves intersect on a graph.

Key Terms and Formulas

• Equilibrium Price: The price at which quantity demanded equals quantity supplied.

• Equilibrium Quantity: The quantity bought and sold at the equilibrium price.

Step-by-Step Guidance

1. Locate the point where the supply and demand curves intersect on the graph.

2. Read the price at this intersection point (equilibrium price).

3. Read the quantity at this intersection point (equilibrium quantity).

4. Match these values to the answer choices, but do not select the final answer yet.

Q30. This diagram shows the demand for trips across a bridge that spans the Hudson River. If the price of crossing the bridge is $6.00, consumer surplus is

Background

Topic: Consumer Surplus

This question tests your understanding of how to calculate consumer surplus using a demand curve and a given price.

Key Terms and Formulas

• Consumer Surplus: The difference between what consumers are willing to pay and what they actually pay.

• Formula (for a straight-line demand curve):

Step-by-Step Guidance

1. Identify the maximum price consumers are willing to pay (the vertical intercept of the demand curve).

2. Find the quantity of trips demanded at the price of $6.00.

3. Calculate the area of the triangle formed between the demand curve and the price line at $6.00.

4. Set up the calculation for consumer surplus, but do not compute the final value yet.
