Example Finance Problem: Mrs. Johnson would like to invest her savings = $20,500 in government Bonds paying 5.5% and Stocks which are expected to pay 8% If she would like to get an income from her investment of $120 per month, How much should she invest in Stocks and how much should she invest in Bonds? Let X = Amount to invest in Bonds Let y = Amount to invest in Stocks => X + Y = 20500 = Total Amount Invested Also => .055*X + .08*Y = 120*12 = 1440 = Yearly Income Type these numbers into the Two Equations above! X = $8,000 = Bonds Y = $12,500 = Stocks |
