Wendell invests $10,000 in a stock portfolio made up of Petroleum Special at $30 per share, New shoes at $12 per share, and Capital beans and Sprouts at $2.50 per share. He places 60 percent of the money in P.S., 30 percent in N, and 10 percent in B & S. With market values changing (P.S. down $3.12, N up 80 percent, and B & S up $0.20), what is his portfolio worth 6 months later?
