11.2. If Classic Oak must pay each worker a market wage of $520 per week, how many workers should the company hire to maximize profit?

Answer 1

4 workers.

Work..Tab..TC.....MC... TR.....MR..Profit

0......0......0........0....... 0.......0.......0

1......6.....520...520... 1200..1200...680

2.....11...1040..520... 2200..1000...1160

3.....15...1560..520... 3000...800...1440

4.....18...2080..520... 3600...600...1520

5.....20...2600..520... 4000...400...1400

Answer 2

The simplest way to approach this if you don't have a formula is to calculate profit for each

1:  6(200) - 1(520) = 680

2: 2200 - 1040 = 1160

3: 3000 - 1560 = 1440

4: 3600 - 2080 = 1520

5: 4000 - 2600 = 1300

Max profit is 1520 at 4 employees

Answer 3

1-680  2-1160  3-1440  4-1520  5-1400

That's what I got for the profit(revenue-wage*amount of workers) at the different production levels.  So, 4 maximizes profit.
