Question 462422
I'm assuming p and q are price and quantity produced/sold...?


Anyway, the equilibrium price occurs when the two lines intersect, or when the amount demanded equals the amount supplied. To find p, we add the two equations together so that the q's cancel:


125p - q - 250 = 0
100p + q - 1100 = 0
--------------------
225p - 1350 = 0


225p = 1350
p = 6 (dollars or whatever currency)
