Stutz Department Store will buy 10 pairs of sunglasses if the price is $81 per pair and 30 pairs if the price is $31. The supplier of the sunglasses is willing to provide 35 pairs if the price is $86 per pair but only 5 pairs if the price is $26. Assuming that the supply and demand functions for the sunglasses are linear, find the market equilibrium point.
This question sounds harder than it really is. All it's really asking you to do is find the point of intersection of two lines... but you have to determine the lines in question.
