19. Janet invested $26,000, part at 6% and part at 3%. If the total interest at the end of the year is $1,080, how much did she invest at 6%?

$11,000
$10,000
$9,000
$16,000

If it $16,000 was invested at 6%, that would leave 10,000 earning 3%, and the total annual interest would be 960 + 300 = 1260.

Try a lower number earning 6%. One of the choices will work.
