The annual income of the certificate of deposit is $200 more than the annual income of the mutual fund. How much is invested in each type of investment?

Answer provided by our tutors

let


c = the money invested in a certificate of deposit paying 12%

m = the money invested in a mutual fund paying 8%


father invests $10,000 in two separate investments


c + m = 10000


the annual income of the certificate of deposit is $200 more than the annual income of the mutual fund


(12/100)*c = 200 + (8/100)m


0.12*c = 200 + 0.08m


by solving the system of equations


c + m = 10000

0.12*c = 200 + 0.08m


we find


c = $5,000


m = $5,000
