Answer:

short-term: $90,000
long-term: $70,000

Step-by-step explanation:

Let x represent the amount borrowed on the short term. Then 160000-x is the amount of the long-term note. The total interest is ...

0.11x +0.08(160000-x) = 15500

0.03x + 12800 = 15500 . . . . simplify

0.03x = 2700 . . . . . . . . . subtract 12800

x = 2700/.03 = 90,000 . . . . short-term note

160,000 -90,000 = 70,000 . . . . long-term note

The short-term note was for $90,000; the long-term note was for $70,000.

Step-by-step explanation:

A quadratic function has the form of ;

f(x) = ax²+bx+c where a, b and c are real numbers and a≠0

For this case, equation y=0.9673x²-0.8475x+10.4334 models a quadratic function where a>0 thus the parabola opens upwards
