Let S = $55, K = $65, r = 4% (continuously compounded), d = 2%, s = 35%, and T = 2. What are the appropriate values of u and d to build a 2-period binomial stock price tree? (Use the formulas from the main part of the chapter and lecture notes, not the alternative formulas in the appendix.)

	a.	u = 1.4477; d = 0.7189
	b.	u = 1.3203; d = 0.6283
	c.	u = 1.6055; d = 0.5306
	d.	u = 1.8328; d = 0.9102
	e.	u = 1.2856; d = 0.5766
