Suppose you purchase 1,100 shares of stock at $49 per share with an initial cash investment of $26,950. The call money rate is 5 percent and you are charged a 1.5 percent premium over this rate. Ignore dividends.

a. Calculate your return on investment one year later if the share price is $57. Suppose instead you had simply purchased $26,950 of stock with no margin. What would your rate of return have been now? (Do not round intermediate calculations. Enter your answers as a percent rounded to 2 decimal places.)

b. Calculate your return on investment one year later if the share price is $49. Suppose instead you had simply purchased $26,950 of stock with no margin. What would your rate of return have been now? (A negative value should be indicated by a minus sign. Do not round intermediate calculations. Enter your answers as a percent rounded to 2 decimal places.)

c. Calculate your return on investment one year later if the share price is $33. Suppose instead you had simply purchased $26,950 of stock with no margin. What would your rate of return have been now? (A negative value should be indicated by a minus sign. Do not round intermediate calculations. Enter your answers as a percent rounded to 2 decimal places.)
