Solution

In case of two goods, a consumer strikes equilibrium when

`(MU_x)/P_x=(MU_y)/P_y`

Given that

`(MU_x)/P_x=4/3=1.33`

`(MU)/P_y=3/3=1`

Here, `(MU_x)/P_x>(MU_y)/P_y`

Thus, if a consumer is not in equilibrium, then the consumer increases the consumption of Good X and decreases that of Good Y to reach the equilibrium.
