Answer the question on the basis of the following two schedules, which show the amounts of additional satisfaction (marginal utility) that a consumer would get from successive quantities of products J and K.

Units of J MU_j Units of K MU_k

1 56 1 32

2 48 2 28

3 32 3 24

4 24 4 20

5 20 5 12

6 16 6 10

7 12 7 8

What level of total utility is realized from the equilibrium combination of J and K, if the consumer has a money income of $52 and the prices of J and K are $8 and $4, respectively?
