Savion's aunt gave him $25 for his birthday with the condition that Savion buys himself something. In deciding how to spend the money, Savion narrows his options down to four choices: Option 1, Option 2, Option 3, and Option 4. Each option costs $25. Finally, he decides on Option 2. The opportunity cost of this decision is
the value to Savion of the option he would have chosen had Option 2 not been available.
Aiden and Zaria charge people to park on their lawn while attending a nearby craft fair. At the current price of $10, six people park on their lawn. If they raise the price to $15, they know that only five people will want to park on their lawn. Whether they have six or five cars parked on their lawn does not affect their costs. From this information it follows that
they would do better charging $15 than $10.

Refer to Figure 4-8. All else equal, an increase in the income of buyers who consider turkey to be an inferior good would cause a move from

Suppose the income of buyers in a market for an inferior good decreases and a technological advancement occurs also. What would we expect to happen in the market?
Equilibrium quantity would increase, but the impact on equilibrium price would be ambiguous.
Suppose the number of buyers in a market increases and a technological advancement occurs also. What would we expect to happen in the market?
Equilibrium quantity would increase, but the impact on equilibrium price would be ambiguous.
Savion is restoring a car and has already spent $4,000 on the restoration. He expects to be able to sell the car for $5800. Savion discovers that he needs to do an additional $2,400 of work to make the car worth $5,800 to potential buyers. He could also sell the car now, without completing the additional work, for $3,800. What should he do?
He should sell the car now for $3,800.

People respond to incentives.
Refer to Figure 4-10. Which of the following movements would illustrate the effect of an increase in the incomes of parents with school-aged children on the market for soccer lessons?

What will happen to the equilibrium price and quantity of new cars if the price of gasoline rises, the price of steel rises, public transportation becomes cheaper and more comfortable, and auto-workers negotiate higher wages?
Quantity will fall, and the effect on price is ambiguous.
Which of the following events would cause the price of oranges to fall?

Which of the following demonstrates the law of supply?
When ketchup prices rose, ketchup sellers increased their quantity supplied of ketchup.
Refer to Figure 4-6. The shift from S' to S in the market for chocolate cake could be caused by
an increase in the price of butter.
Equilibrium quantity must decrease when
both demand and supply decrease.
Suppose you like to make, from scratch, pies filled with bananas and vanilla pudding. You notice that the price of bananas has increased. As a result, your demand for vanilla pudding would
decrease
Refer to Table 4-4. If these are the only four sellers in the market, then when the price decreases from $8 to $6, the market quantity supplied
decreases by 12 units
Refer to Figure 4-1. It is apparent from the figure that the
demand for the good conforms to the law of demand.
At the equilibrium price, the quantity of the good that buyers are willing and able to buy
exactly equals the quantity that sellers are willing and able to sell.
Soup is an inferior good if the demand
for soup falls when income rises.
Suppose the cost of operating a 75-room hotel for a night is $6,000 and there are five empty rooms for tonight. If the marginal cost of operating one room for one night is $40, the hotel manager should rent one of the empty rooms only if a customer is willing to pay
more than $40; because the marginal benefit will exceed the marginal cost.
Efficiency
refers to how much a society can produce with its resources. Equality refers to how evenly the benefits from using resources are distributed among members of society.
