Explanation / Answer

The consumer equilibrium is 7 magazines and 6 Cds with a budget constraint of $88.

Marginal Utility for magazines at consumer equilibrium = 736 - 716 = 20

Dollars spent on the 7th magazine = $4

Marginal Utility per dollar spent on magazines at consumer equilibrium = 20 / 4 = 5 units.
