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 XTels price fall before you get a margin call? (Round your answer to 2 decimal places.)
