a. (2 pts.) What is demand elasticity in the \$10 – \$20 price range? Is demand elastic, inelastic, or of unitary elasticity? Calculate the value and show all of your work. Be sure to use the midpoint equation used to determine elasticity.

8. Question : (TCO C) Answer the next question on the basis of the following cost data for a purely competitive seller:

Total Product TFC TVC
0 \$200 \$0
1 200 70
2 200 120
3 200 150
4 200 220
5 200 300
6 200 390
Refer to the above data. If the product price is \$65 at its optimal output, exactly how many units should be produced to maximize profits or minimize losses? How much will the profit or loss be? Show all calculations.

9. Question : (TCO C) Answer the next question on the basis of the following cost data for a purely competitive seller:

2 45 320
3 45 450
4 45 620
5 45 800
6 45 990
Refer to the above data. If the product price is \$185 at its optimal output, exactly how many units should be produced to maximize profits or minimize losses? How much will the profit or loss be? Show all calculations.

10. Question : (TCO C) A firm has Total Costs (TC) of \$10,000 over the next three months (TOTAL for the 3 months – not per month), of which \$6,000 are fixed costs (TFC) for rent on its lease that cannot be broken. If it stays in business over those months, then the firm will collect only \$5,000 in revenues (TR). So, considering only this information, should they stay in business for those three months or should they close down right now? Provide your reasoning.
