Answer:

$9,000 at 15%
$4,000 at 10%

Step-by-step explanation:

Let x represent the amount borrowed at 15%. Then the amount borrowed at 10% is (13000-x). The interest at the end of the year is ...

0.15(x) + 0.10(13000 -x) = 1750

0.05x = 1750 -1300 . . . . . . . . . . . . simplify, subtract 1300

x = 450(20) = 9000 . . . . . . . . . . multiply by 20

$9,000 was borrowed at 15%; $4,000 was borrowed at 10%.
