Answer:

$10,000 at 5%
$22,000 at 6%

Step-by-step explanation:

Let x represent the amount invested at 6%. Then 32000-x is the amount invested at 5%, and the total interest earned is ...

0.06x +0.05(32000 -x) = 1820

0.01x +1600 = 1820 . . . . simplify

0.01x = 220 . . . . . . . . . . subtract 1600

x = 22,000 . . . . . . . . . . . multiply by 100

32000 -x = 10,000

Phyllis invested $22,000 at 6% and $10,000 at 5%.
