Atotal of $32,000 is invested in two municipal bonds that pay 4.25% and 6.25% simple interest. the investor wants an annual interest income of $1680 from the investments. what amount should be invested in the 4.25% bond?

$16000 invested in 4.25%  and 16000 invested in 6.25%

Step-by-step explanation:

Let x be the amount invested in 4.25%  and y be the amount invested in 6.25%

4.25%= 0.0425

6.25%= 0.0625

subtract x from both sides

total interest earned is 1680

Now solve for x  and y

subtract 2000 from both sides

divide by -0.02 from both sides

x=16000

25% is the answer
