Final answer:
An inconsistent system of cost and revenue functions means that no break-even point exists, and thus the business will never profit as the cost always exceeds the revenue.
Step-by-step explanation:
When the system of equations containing the revenue and the cost functions is an inconsistent system, it implies that there is no level of production at which the total cost and total revenue are equal. Therefore, no break-even point exists for the business. In practical terms, this means that the business will never profit (option c), because the total revenue is always less than the total cost at any level of production, indicating that the business would incur losses irrespective of how many units are sold.
