If the supply equation is given as Q=-200+10P, the price elasticity of supply between R40 and R50, calculated using the arc elasticity of demand, is?

If Qs = -200 + 10P, P1 = R40, P2 = R50, Q1 = -200 + 10*40 = 200, Q2 = -200 + 10*50 = 300, then the price elasticity...

If a decrease in price from R50 to R40 causes the quantity demanded to increase from 2500 to 3000 units, then using the arc elasticity of demand, the price elasticity...

1) PED = (% change in quantity demanded) / (% change in price) = = ((3000-2500)/2500) / ((40-50)/50) = -1

E_d^p=((Q2-Q1)/((Q2+Q1)/2))/((P2-P1)/((P2+P1)/2))=((3000-2500)/((3000+2500)/2))/((40-50)/((40+50)/2))=0.18/(-0.22)=-0.82
