Answer:
- $17,500 at 14%
- $16,000 at 12%
Step-by-step explanation:
Let x represent the amount loaned at 14%. Then the total interest earned is ...
0.14x +0.12(33,500 -x) = 4,370
0.02x = 350 . . . . . . . . . . subtract 4020 and simplify
x = 17500 . . . . . . . . . divide by 0.02
The amount loaned at 12% is $33,500 -17,500 = $16,000.
$17,500 was loaned at 14%
$16,000 was loaned at 12%
