Suppose that when the price of corn is $2 per bushel, farmers can sell 10 million bushels. When the price of corn is $3 per bushel, farmers can sell 8 million bushels. Which of the following statements is true? a. The demand for corn is income inelastic, and so an increase in the price of corn will increase the income of corn farmers. b. The demand for corn is income elastic, and so an increase in the price of corn will increase the income of corn farmers. c.

b

When demand is elastic in the current price range, a. an increase in price would increase total revenue because the decrease in quantity demanded is less than the increase in price. b. an increase in price would decrease total revenue because the decrease in quantity demanded is greater than the increase in price. c. a decrease in price would decrease total revenue because the increase in quantity demanded is smaller than the decrease in price. d. a decrease in price would not affect the total revenue.
