1) Price elasticity of demand is computer as the arc elasticityby:
a) dividing the slope of the demand curve by the average value ofeach variable between two points
b) dividing the slope of the demand curve by the average value ofeach variable at one point
c) calculating percentage changes relative to the value of onevariable at one point
d) calculating percentage changes relative to the average value ofeach variable between two points

a) 0
b) -0.5
c) -1
d) -2
