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