Differential Analysis for a Lease or Sell Decision Granite Construction Company is considering selling excess machinery with a book value of $282,400 (original cost of $400,700 less accumulated depreciation of $118,300) for $275,700, less a 5% brokerage commission. Alternatively, the machinery can be leased for a total of $284,900 for five years, after which it is expected to have no residual value. During the period of the lease, Granite Construction Company's costs of repairs, insurance, and property tax expenses are expected to be $24,600. Required:
Prepare a differential analysis, dated November 7 to determine whether Granite should lease (Alternative 1) or sell (Alternative 2) the machinery.

Suppose that xtel currently is selling at $40 per share. you buy 500 shares using $15,000 of your own money, borrowing the remainder of the purchase price from your broker. the rate on the margin loan is 8%. a. what is the percentage increase in the net worth of your brokerage account if the price of xtel immediately changes to (a) $44; (b) $40; (c) $36? (leave no cells blank - be certain to enter "0" wherever required. negative values should be indicated by a minus sign. round your answers to 2 decimal places.) b. if the maintenance margin is 25%, how low can xtel’s price fall before you get a margin call? (round your answer to 2 decimal places.) c. how would your answer to requirement 2 would change if you had financed the initial purchase with only $10,000 of your own money? (round your answer to 2 decimal places.) d. what is the rate of return on your margined position (assuming again that you invest $15,000 of your own money) if xtel is selling after one year at (a) $44; (b) $40; (c) $36? (negative values should be indicated by a minus sign. round your answers to 2 decimal places.) e. continue to assume that a year has passed. how low can xtel’s price fall before you get a margin call? (round your answer to 2 decimal places.)
