## I am a newbie in Macroeconomics~ I need some help~

1)Sherman Peabody earns a monthly salary of \$1,500, which he receives at the beginning of each month. He spends the entire amount each month at the rate of \$50 per day. (Assume 30 days in a month.) The interest rate paid on bonds 10 % per month. It costs \$4 every time Peabody sells bond.

1. Describe briefly how Mr. Peabody should decide how much money to hold.
2. Calculate Peabody’s optimal money holding. You can round to the nearest \$0.50, and you need to consider only average money holding of more than \$100
3. Suppose the interest rate rises to 15 percent. Find the Peabody’s optimal money holding at this new interest rate. What will happen if the interest rate increases to 20 percent?
4. Graph your answer to b. and c. with interest rate on the vertical axis and the amount of money demanded on the horizontal axis. Explain why your graph slopes downwards.

Someone help me~

This isn't a homework help forum.

There are actually many economics help forums, you should google for some.

Here's a novel idea, why not open up that textbook/class lecture notes, study the material and try to draw your own conclusions?
