Question

Country Day's scholarship fund receives a gift of $ 150000. The money is invested in stocks, bonds, and CDs. CDs pay 3.5 % interest, bonds pay 4.9 % interest, and stocks pay 11.7 % interest. Country day invests $ 55000 more in bonds than in CDs. If the annual income from the investments is $ 12310 , how much was invested in each vehicle?

Answer 1

C - money invested in CDs

B - money invested in Bonds

S - money invested in Stocks

You will need to solve this system of equations:

C + B + S = 150,000

B = C + 55,000

0.035C + 0.049B + 0.117S = 12,310

Good luck!
