2. Suppose the price demand curve for a particular good is P = $30 - Q, where P is the price and Q is the quantity.  Also suppose the price supply curve is P = $6 + Q.  At which price and quantity will the good be sold (assuming a free market)?

:

:Given: P= 30-Q; P= 6+Q. So, P=P, and 30-Q = 6+Q, which equals 12. So, Q=12. Inserting this answer back into the first original equation (P= 30-Q) gives me, P=18. '''So, the Quantity is 12 and the Price is $18.'''  (Trisha)

3. When the '''''supply''''' of a good or service increases, such as increasing the number of oil wells, what happens to the market price of oil?  Explain.  When the '''''demand''''' for a good a good or service increases, such more people driving cars that need gasoline (refined oil), what happens to the market price of oil?  Explain.
