A few days ago, Deanna Watson purchased 100 shares of Microsoft common stock for $35 per share. Deanna is single, and her taxable income (after all deductions and exemptions) is $75,000. Compute the capital gains tax liability for the following situations:

a. Deanna holds the stock for five months and then sells it for $40 per share.

b. Deanna sells the stock for $45 per share 13 months after she purchased it.

c. Deanna doesn't sell the stock until four years from today, when the selling

price is $105 per share.

(Please show work! thank you)
