Marginal Utility (MU) of a is 30 and sells for 2$What is the MU of b = 4 c = 3 d = 1 e = 5?

Question

The only additional detail is the Bob is in consumer equilibrium

Answer 1

Since equilibrium condition is given by MU1/P1=MU2/P2... =MUn/Pn

So you have following rules:

a=2

b=4

c=3

d=1

e=5

And equations (MU's are capital letters):

A=30

B, C, D, E, are unknown.

A/a=B/b=C/c=D/d=E/e

30/2=B/4=C/3=D/1=E/5

B/4=15

B=60

C/3=15

C=45

D/1=15

D=15

E/5=15

E=75

Answer: MU equals:

B=60

C=45

D=15

E=75
