U. (8 points) The total demand for money is equal to the transactions demand plus the asset demand for money. 1. Assume that each dollar held for transactions purposes is spent on the average 4 times per year to buy final goods and services.

Using your answer to part 1, complete the table to show the total demand for money at various rates of interest. Interest rate Asset demand Total demand (in %). (billions). (billions) 50 90 130 170 3. If the money supply is 220 billion, what will be the equilibrium rate of interest? 4. If the money supply rises to 300, will be the new equilibrium rate of interest? 5. If GDP rises, what will be the effect on the rate of interest
