Math 1070Q Prof. Andrew Jaramillo Week Two Notes Supply, Demand, and Equilibrium Ex 4) The demand equilibrium is p=-2.5x+1692. A firm supplies 50 computers to a market if the price is $676/computer. The firm will supply 50 more computers if they are priced at $826/computer. Find the supply equation and the equilibrium point. Step 1) Find the supply equation. X= # of computers, p=price/computer, *p=mx+b *Supply Equation: p=3x+526
