Answer:
$35,000
Step-by-step explanation:
Let x represent the amount borrowed from Bank A. Then (55000-x) is the amount borrowed from Bank B. Kim's total 1-year interest is ...
0.08x + 0.11(55000 -x) = 5000
-0.03x + 6050 = 5000 . . . . . simplify
-0.03x = -1050 . . . . . . . . . . . . subtract 6050
x = 35,000 . . . . . . . . . . . . . . . divide by -0.03
Kim borrowed $35,000 from Bank A.
