Kermmit buys only two good: Cranberriess (c) and Kiwis(k). His preferences for cranberries and Kiwis are given by the utility function Uc,k=20*C*K. The marginal
utilities of cranberries and kiwis are MUc=20k and MUk=20c, respectively. a. The marginal utility of cranberries (MUc) (increase, decrease, remain constant) as
Kermit consumes more cranberries. b. Kermit’s marginal rate of substitution of cranberries for Kiwis(MRSc,k) is equal to (c/k, 20, 40/c^2*k^2), K/c, (c+k)/20, root
ck ) c.When Kermit consumes three cranberries and five Kiwis, his utility level is (400, 300, 600, 150, 550) and his marginal rate of subsitution of cranberries
for kiwis (MRSc,c) is equal to 1.18 kiwis per cranberry, 3.87 kiwis per cranberry, 20kiwis per cranberry, 0.6 kiwis per cranberry, 0.4 kiwis per cranberry).
