1) Suppose a department store has a sale on its silverware. If the price of a place-setting is reduced from $30 to $20 and the quantity demanded increases from 3,000 place-settings to 5,000 place-settings, illustrate what is the price elasticity of demand for silverware?

a) 0.8

3) An increase in price will result in an increase in total revenue if demand is:

a) unit elastic.

b) perfectly elastic.

6) In the run up to the war in Iraq which began in 2003, one of the many concerns raised was which a war could result in a decrease in the supply of oil. At the same time, the U.S. economy was having a hard time recovering from the most recent recession and, as a result, incomes of many consumers had decreased (due to layoffs, wage cuts, and so forth). All else constant, it was reasonable to predict, with certainty, which the combination of these two factors would cause the equilibrium:

a) quantity of oil to increase.

b) quantity of oil to decrease

c) price of oil to increase.

d) price of oil to decrease

8) The market demand for a good is determined by vertically summing the demand curves of individual consumers. (Horizontal summation will be there)

a) True
