Explanation Given: Sachi and his financial planned to invest $25,000 in the three investment categories. The rate of interest earned in the Treasury bills, municipal bonds and corporate bonds are 3%, 5% and 9% simple interest annually. Sachi expected to earn $1210 per year form the investment and she wants to invest in treasury bills to be $7000 more than her investment in corporate bonds. Calculation: Step: 1 Obtain amount of Treasury bills investment, municipal bounds investment and corporate bonds investment. Step: 2 Let x , y and z represents the amount invest in Treasury bills, municipal bounds and corporate bonds respectively. Step: 3 Here, the total amount Sachi invest is $25,000. The above statement can be written as x + y + z = 25 , 000 (1) Also, the rate of interest earned in the Treasury bills, municipal bonds and corporate bonds are 3%, 5% and 9% simple interest annually and the total amount of interest earned from the investment is $580. The above statement can be written as 3 100 x + 5 100 y + 9 100 z = 1210 . That is, 0.03 x + 0.05 y + 0.09 z = 1210 . (2) Sachi wants to invest in treasury bills to be $7000 more than her investment in corporate bonds. The above equation can be written as x = z + 7000 . That is, x − z = 7000 . (3) Step: 4 To solve the system { x + y + z = 25 , 000 0.03 x + 0.05 y + 0.09 z = 1210 x − z = 7000 . Multiply the equation (1) by 0.05. Then, subtract the equation (1) and (2). 0.05 x + 0.05 y + 0.05 z = 1250 0.03 x + 0.05 y + 0.09 z = 1210 _ 0.02 x + 0.00 y − 0.04 z = 40 ( 4 ) Multiply the equation (3) by 0.04. Then, subtract the equation (2) and (3). 0.04 x − 0
