Let x be the amount invested at 3%
Then, (14,000-x) will be the amount invested at 6%.
Interest earned at 3% will be:
Interest earned at 6% will be:
Total interest earned is given to $570, thus we have:
Amount invested at 6% will be 14,000 - 9,000 = $5,000.
Hence, the amount invested at 3% and 6% are $9,000 and $5,000 respectively
