SCENARIO B: Suppose that due to favorable economic conditions, the price that this firm can sell its product
for rises to $22.
For question 1. Fill in Table B - Each box is worth ½ point for a total of 9 points for Table B
TABLE B- The wage is still $150 and the price of output (Q) is now $22.

DOWNLOAD AND PRINT GRAPHING TEMPLATE (available in the homework 3 instructions). This
template already shows the outcome from scenario A. You will be adding results from scenario B to
these graphs.
(2 points) Using Scenario B/Table B, go to Graph 1 . Label the new profit maximizing Q and L combination on
the production function as point B.

Correct Answer(s):
6.
(3 points) Using Scenario B/Table B, go to Graph 2 and draw this firm’s new MRP curve (remember that MRP
= P* MPL, and since price changed, we know we have a new MRP curve!). Shade in the new area of profit.
Also label the new profit maximizing point as letter B.

7.

(3 points) Using Scenario B/Table B, draw this firm’s Supply curve on Graph 3 . You should construct a supply
curve as we did in lecture with point A representing the original price and output combination from scenario A
(original price was $20 combined with the profit maximizing Q of 28) and point B representing the price and
output combination after the change in economic conditions in Scenario B (price rose to $22, and the profit
maximizing Q you found in your answer for #2 above). Connect the two points and label your supply curve.
