Explanation / Answer

= 9/4 = 2.25

cross price elasticity of supply = (change in quantity barley/quantity barley)/(change in price wheat/price wheat)

= ((99-101)/99)/((2.46-2.34)/2.34)

= -13/33 = -0.39 = -13/33 = -0.39
price elasticity of demand for labor = (change in employment/employment)/(change in wage/wage) = ((6.75-6.25)/6.25)/((4900-5100)/4900) = -49/25 = -1.96 = -49/25 = -1.96
