Answer: The explicit costs of selling pianos are:
1) Wholesale manufacturing costs of $430,000
2) Wages and utility Bills of 301,00
The implicit costs of selling pianos are:
1) $15000 rent per year
2) $50,000 annual salary.
Explanation: Implicit costs are the opportunity costs of doing a business or the profits that the owner decides to give up because of doing business.
In this case the implicit costs are the rent he would receive on the showroom instead of selling pianos there and the salary he could earn as an divisor instead of selling pianos. These are the opportunities that he has to forgo in order to do the piano business.
Explicit costs are costs which are directly related tot the business therefore they include the manufacturing cost and wages and utility bills as they are directly related to the business.
