Answer:

  • $17,500 at 14%
  • $16,000 at 12%

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%
