Which of the following describe a product with an inelastic demand?

An appointment with a dentist.

Which method for calculating elasticity uses the values of the average price and average quantity?

The percent change approach

Which of the following goods represent a cross-price elasticity likely greater than zero?

The substitute goods of blueberries and strawberries.

What happens to total revenue (TR) if the price rises on a product with demand that is price inelastic?

Total revenue will rise.

Good news for an industry that typically produces inelastic goods can

be bad news for individual producers because when these factors shift the supply curve to the right it decreases total revenues.

If you divide the change in quantity by the original quantity, you are calculating the

change in elasticity.

increasing

When income increases and demand for a good falls, the good is considered a

inferior good.

If the elasticity of demand for a company's product is estimated to be 1.72, what would you advise the company to do if their objective is to increase revenue?

If you divide the change in quantity by the original quantity, you are calculating the

percentage change.

When a 10% increase in income causes a 4% increase in quantity demanded of a good

the income elasticity is .4 and the good is a normal good.

Demand is relatively inelastic if ________.

there are foreign production inputs

You are the manager of the public transit system. You are informed that the system faces a deficit, but you cannot cut service, which means you cannot cut costs. Your only hope is to increase revenue by increasing fares. You are advised that the estimated price elasticity of demand for the first few months after a price change is about −0.3. Select the statement that best describes the results of raising the fare in the short run.

Total revenue rises immediately after the fare increase, since demand over the immediate period is price inelastic.

A tax is imposed on chewing gum. Consumers pay all of the tax while the producers pay none of the tax. If you were to draw a graph you would see that the demand curve

perfectly inelastic.

When supply is inelastic and demand is elastic, the tax incidence falls on ________.

when there are many substitutes

Given that total revenue = price x quantity, what will happen to total revenue if price increases when demand is elastic?

It will decrease.

It would increase by 0.625.

Suppose the price elasticity of supply has been calculated as 0.80 for a particular product and the price increases by 5%. What would happen to the quantity supplied?

It would increase by 8%.

Kelly's salary was bumped up this year after she accepted the new position of Vice President of Marketing. Her income increased from $65,000 to $83,000. Last year Kelly purchased 2 used cars. This year she purchased 0 used cars. Assuming that all of the other things remain constant, what type of a good is a used car and what type of income elasticity of demand does Kelly have?

A used car is an inferior good and the income elasticity of demand is 8.22.

What happens to total revenue (TR) if the price decreases on a product with demand that is price elastic?

Total revenue will rise.

income elasticity is .33 and the good is a normal good.

inelastic, greater

the price of a product times the number of units sold; TR=P x Qd

Suppose the price of apples increase by 20%, resulting in consumers to purchase 15% more pears. Given this information, it appears that

cross-price elasticity of pears is 0.75.

The percentage change in quantity divided by the percentage change in price is the

elasticity.
