  1. Use the following table showing a monopolist’s demand schedule and short-run total cost schedule to answer the questions below.

 

Price Quantity Total cost
$11 0 $400
10 60 800
9 90 890
8 130 1,050
7 166 1,230
6 196 1,440
5 210 1,552

 

  • To maximize profit the firm will set a price of$__8_and sell _130____units output.
  • Profit (loss) at the profit-maximizing output is $_10
  • If the firm reduces price $1 from the profit-maximizing level, marginal revenue is $3.39_ and marginal cost is $5.00
  • If the firm reduces price $1 from the profit-maximizing level, profit (loss) will be $68.00
