Fred invested 350 in the stock market. The value of his investment increased by 25 and then later decreased by 40. How much did the investment decrease in value from the time he first invested?

Total Investment= $35000+ $40000=$75000

Portfolio Beta = [(35000/75000) X .08] + [(40000/75000) X 1.4]

= 0.78 Answer I came up with was 350 + 25% = 437.5 - 40% = 262.5
