What will be an ideal response?

a.Interest= principal × interest rate = $10,000 × 0.05 = $500 b.Taxes= interest × tax rate = $500 × 0.40 = $200 c.After-tax nominal income= interest − taxes = $500 − $200 = $300 d.Loss of principal to inflation= principal × inflation rate = $10,000 × 0.02 = $200 e.Real interest income= nominal interest − loss of principal to inflation = $500 − $200 = $300 f.After-tax real income= real interest income − taxes = $300 − $200 = $100 or After-tax real income= after-tax nominal income − loss of principal to inflation = $300 − $200 = $100 g.Of the $500 in nominal interest income, (1) Loretta gets $100/$500 = 20 percent; (2) the government gets taxes of $200/$500 = 40 percent; and (3) inflation gets $200/$500 = 40 percent.
