2.LetbasketAbe(x,y)=(9,11).Foreachofthefollowing

utility functions (a-d), answer the following questions (i- iv):

i)Determine the utility at basketA

ii)Writeouttheequationfortheindifferencecurvethat

basketAlies on. (simplify toyequals some function ofx)

iii)Find 3 other points that lie on the sameindifference curve asA(can contain fractions ordecimals).

iv) Calculate theMRS_x,yat basketAand give an eco-

nomic interpretation of what the means in words.

(a)U(x, y)=4xy.

(b)U(x, y)=6x²+2y².

(c)U(x,y)=7x1/2+3y.

(d)U(x, y)=5x+10y.
