Suppose you owe ​$1200 on your credit card. The annual percentage rate​ (APR) is 18​%, compounded monthly. The credit card company says your minimum monthly payment is ​$21.82. a. If you make only this minimum​ payment, how long will it take for you to repay the ​$1200 balance​ (assuming no more charges are​ made)? b. If you make the minimum payment plus ​$10.01 extra each month​ (for a total of ​$31.83​), how long will it take to repay the ​$1200 ​balance? c. Compare the total interest paid in Part​ (a) with the total interest paid in Part​ (b).

The following information indicates percentage returns for stocks L and M over a 6-year period:

In combining [L−M] in a single portfolio, stock M would receive 60% of capital funds. Furthermore, the information below reflects percentage returns for assets F, G, and H over a 4-year period, with asset F being the base instrument: Year Asset F Returns Asset G Returns Asset H Returns

Using these assets, you have a choice of either combining [F−G] or [F−H] in a single portfolio, on an equally-weighted basis.

Required: Calculate the absolute percentage difference in the coefficient of variation (CV) between the stock portfolio [L−M] and the portfolio which outlines the optimal combination of assets
