Istarted a business last year. my revenues were $100,000. my rent and materials costs were $60,000. my best alternative was and is to go to work for a company in a job that would pay me $30,000. the "true" profits from my business were . $10,000b. $30,000c. $40,000d. $90,000e. $240,000

$10,000

Explanation: True profits are the profits which takes into consideration the opportunity cost of choosing an alternative. Opportunity cost refers to the loss of profit incurred by a firm or an individual while choosing best alternative over the second best alternative.

In the given case, the individual could have earned $30,000 from the job so it is his opportunity cost that must be deducted from the revenues to ascertain the profit. That is :-

Profit =  revenue - materials - opportunity cost

         = $100,000 - $60,000 - $30,000

         = $10,000
