a)by use of diagrams where appropriate differentiate between Marshallian and Hicksian demand curves.
b)The utility function for a consumer is given as follows:
U=X0.3Y0.7.
i)derive the Hicksian demands for X and Y.
ii)give economic interpretation of the Lagrangian multipliers
iii)use the result from part (i)and (ii)for good X to show that the sky equestio hold
