Here is a demand function: $Q=9-6P$ On the answer sheet circle your choice for its marginal

revenue $($MR$)$ function.

Circle your choice for the quantity that will maximize total revenue for the function in $5($above$).$

Suppose the price elasticity of demand for bread is $1\mathrm{.}00.$ If the price of bread rises by $20\%,$ the

quantity demanded will decrease by:

Suppose that a $10\%$ decrease in income causes a $20\%$ increase in demand for good X $.$ The

coefficient of income elasticity of demand is:

When the price of a weekly magazine decreases from $$2\mathrm{.}00$ to $$1\mathrm{.}50$ the quantity demanded

increases from $90,000$ to $150,000.$ The price elasticity of demand in this range is:

If the elasticity of supply of crude oil is $1\mathrm{.}5,$ how much will production have to increase to

match a $10\%$ price increase?

Demand for X decreases from $100$ to $50$ when the price of Y decreases from $$6$ to $$5.$ The

cross$-$price elasticity of demand is:
