Total profit from marginal profit. A firm is able to determine that its marginal profit, in dollars, from producing $x$ units of an item is given by $$P^{\prime}(x)=200 e^{-0.032 x}$$ Suppose that it were possible for the firm to make infinitely many units of this item. What would its total profit be?

Total profit from marginal profit. A firm is able to determine that its marginal profit, in dollars, from producing $x$ units of an item is given by $$P^{\prime}(x)=200 e^{-0.032 x}$$
Suppose that it were possible for the firm to make infinitely many units of this item. What would its total profit be?

Key Concepts

Marginal Profit

Marginal profit refers to the instantaneous rate of change of total profit with respect to the number of units produced. In calculus terms, it is the derivative of the profit function. This concept is essential in economics for understanding how small changes in production affect overall profitability.

Accumulation through Integration

Integration is the mathematical process used to accumulate quantities, and in this context, it is used to find the total profit from the marginal profit function. By integrating the marginal profit over a range of produced units, one can determine the cumulative profit gained.

Improper Integral

An improper integral involves an integration over an unbounded interval, such as from zero to infinity. This concept is important when calculating total profit if production can continue indefinitely, as it requires evaluating a limit to find the convergence of the integral.

Exponential Decay

Exponential decay functions describe processes where a quantity decreases at a rate proportional to its current value. In the given context, the marginal profit function features an exponential decay term, which affects the accumulation of profit by diminishing the profit earned per additional unit as production increases.
