Question

When the price of a product is p dollars, each, suppose that a manufacturer will supply 2 p −10 units of the product to the market and that consumers will demand to buy 200 −3p units. At the value of p for which supply equals demand, the market is said to in equilibrium. Find the value of p . What is your reply?

Answer 1

2p - 10 = 200 - 3p First you will subtract add 2p to both sides.
+3p + 3p
----------------------
5p - 10 = 200 Then i will add 10 to both sides
+10 + 10
----------------
5p = 210 Now divide both sides by 5 to get the value of p.
/5 /5
---------
p = 42
