Question 84625: The supply equation is Y= 28X + 2025 and the demand equation is Y= -17X + 6120. The equilibrium demand is

A. 45
B. 4573
C. 2025
D. 91

I figured this problem and came up with the values of X = 91 and Y = 4573. Both of these answers are listed above. Which one is the equilibrium demand?, or do I have to continue figuring further to get another answer?? PLEASE assist.

Hello there,
In this case, you are trying to find X because you want the equilibrium equation. Therefore, you equalise the supply and demand equations. Your answer would be 91.
