Rational decisions indeed<span> occur when the marginal benefits of an action equal or exceed the marginal costs. No person would make a decision that would incur a loss in his part. Therefore, in order to say that you were able to have a rational decision, you have to bear in mind the profit you can gain out of it. Example of this is the decision on additional worker. Suppose you are paying $20</span><span> per worker and they produce 5,000 units. If you are to add additional worker, you will incur an additional $20 but it will also increase the production output to 8,000 units. Therefore, it would be a rational decision to employ another worker since the benefits would exceed the cost.</span>
