Answer» Solution :`{:("Initial Price (P) = 1","Initial Expenditure = 80","Initial DD (Q)"(80)/(1)=80),("New Price "(P_(1))=2,"New Expenditure = 96","New DD "(Q_(1))=(96)/(2)=48),(Delta P=1,,Delta Q=-32):}` `PED=(Delta Q)/(Delta P)xx(P)/(Q)=([-]32)/(1)xx(1)/(80)=[-](4)/(10)=[-]0.4` NEGATIVE Sign of ED indicates the inverse relationship between price and QUANTITY demanded. PED = 0.4 [Less than unitary elastic demand or INELASTIC demad] |
