Question 191608
let x and y be the amounts borrowed at 7% and 8.5 % interest respectively
:
x+y=5000..........eq1
.07x+.085y=380....eq 2
:
rewrite eq 1 to x=5000-y and plug this value into eq 2
:
.07(5000-y)+.085y=380
:
350-.07y+.085y=380
:
.015y=30
:
y=2000 dollars at 8.5%
:
x=5000-y=5000-2000=3000 dollars at 7%
