Investment. Part of $25,000 is invested at 10 percent, another part is invested at 12 percent, and a third part is invested at 16 percent. The total yearly income from these three investments is $3,200. Furthermore, the income from the 16 percent investment yields the same amount as the sum of the incomes from the other two investments. How much is invested at each rate?

Let A, B, C be the amounts invested at 10, 12, and 16 percent.
A*.10+B*.12+C*.16=3200
C*.16=A*.10+B*.12
A+B+C=25,000
Can you solve it now?
