Mr. Midas has wealth of $100,000 that he invests entirely in money (a checking account) and government bonds. Mr. Midas instructs his broker to invest $50,000 in bonds, plus $5,000 more in bonds for every percentage point that the interest rate on bonds exceeds the interest rate on his checking account.
Write an algebraic formula that gives Mr. Midas’ demand for money as a function of bond and checking account interest rates.
