Short Answer/Calculation     The table below shows the consumption choices between two goods: running shoes and running shorts. Assume that you have an income of $300, running shoes cost $150, and running shorts cost $30. Fill in the total utility columns, as well as the marginal utility per dollar (MU/$) columns.
