1.Which of the following is consistent with the law of supply?
a.As the price of calculators rises, the supply of calculators increases, ceteris paribus.
b.As the price of calculators falls, the supply of calculators increases, ceteris paribus.
c.As the price of calculators rises, the quantity supplied of calculators increases, ceteris paribus.
d.As the price of calculators rises, the quantity supplied of calculators decreases, ceteris paribus.
2. DVDs and DVD Players are complements. An increase in the price of DVD Players would cause which of the following in the market for DVDs?
a.The equilibrium price and quantity of DVDs would increase.
b.The equilibrium price and quantity of DVDs would decrease.
c.The equilibrium price of DVDs would increase and the equilibrium quantity would decrease.
d.The equilibrium price of DVDs would decrease and the equilibrium quantity would increase.
For number 1, I don't see the difference between a. and c.
1) c is correct. (Mostly semantics, but a change in supply is a shift in the supply curve, a change in quantity supplied is a movement along a curve.
2) go with b. (hint: draw supply and demand curves for DVD's. An increase in DVD Players does what to the Demand for DVD's? )
assume that hamburgers and french fries are complements. if the price of french fries falls, what will happen in the market for hamburgers?
a.there will be a movement from one point to another along the demand curve for hamburgers b.there will be a movement from one point to another along the supply curve for hamburgers c.the demand curve for hamburgers will shift to the right d.the supply curve for hamburgers will shift to the right
Let's go through each question to confirm the correct answers:
1. Which of the following is consistent with the law of supply?
The correct answer is: c. As the price of calculators rises, the quantity supplied of calculators increases, ceteris paribus. This is consistent with the law of supply, which states that as the price of a good increases, the quantity supplied of that good also increases.
2. DVDs and DVD Players are complements. An increase in the price of DVD Players would cause which of the following in the market for DVDs?
The correct answer is: c. The equilibrium price of DVDs would increase and the equilibrium quantity would decrease. Complementary goods are goods that are typically consumed together, so an increase in the price of one (DVD Players) would decrease the demand for the other (DVDs), leading to a decrease in both the equilibrium price and quantity of DVDs.
4. The price of hot dogs changes by 22% and the quantity of hot dogs demanded changes by 25%. This indicates that demand for hot dogs is
The correct answer is: a. Elastic. The percentage change in quantity demanded is greater than the percentage change in price, indicating that demand is elastic. This means that consumers are highly responsive to price changes, leading to a relatively larger change in quantity demanded compared to the change in price.
5. If total revenue increases after a price increase, demand is
The correct answer is: d. Elastic. When total revenue increases after a price increase, it indicates that the quantity demanded increased by a larger percentage than the price, indicating elastic demand. Elastic demand means that consumers are highly responsive to price changes, leading to a relatively larger change in quantity demanded compared to the change in price.
6. Substitutes are goods that people buy
The correct answer is: c. Instead of another product whose price has increased. Substitutes are goods that can be used in place of each other, particularly when one becomes more expensive. When the price of a substitute product increases, people tend to buy the other substitute product instead.
7. If an increase in the price of accordions does not change total revenue from accordion sales, what can we infer about the price elasticity of demand for accordions?
The correct answer is: b. Inelastic. If an increase in price does not change total revenue, it indicates that the quantity demanded is not very responsive to price changes. This suggests that demand for accordions is inelastic, meaning that consumers are not very sensitive to price changes and still buy the same quantity even at a higher price.
So, based on your answers, all of them are correct!
