The price, in dollars, of a certain stock over a 10-day period is given as: price = [19, 18, 22, 21, 25, 19, 17, 21, 27, 29]. Suppose you owned 1000 shares at the start of the 10-day period, and you bought 100 shares every day the price was below $20 and sold 100 shares every day the price was above $25.
