Answer: It is reasonable to assume that a profit-maximizing firm will never operate in the inelastic portion of its demand curve.
Step-by-step explanation:
It should be noted that a firm that profit maximizing will not operate in the inelastic portion of its demand curve because at that point, the firm isn't maximizing profit.
When there's an inelastic demand, an increase in price will bring about a less than proportionate reduction in the quantity of the goods that's demanded. In such case, if the firm operates at the inelastic portion of its demand curve, when it increases price, this will lead to a reduction in income and profit will not be maximize.
