Suppose the market for grass seed can be expressed as
 
  Demand: QD = 100 - 2p
  Supply: QS = 3p
 
  At the market equilibrium, calculate the price elasticities of supply and demand. Use these numbers to predict the change in price resulting from a specific tax.

Answer to Question 1

At p = 20 Q = 60, e = -2  (20/60 ) = -0.67. n = 3  (20/60 ) = 1.
The change in price resulting from a specific tax = n/(n - e)  tax = 1/1.67  tax = 0.6  tax.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
