$55-56$ : Revenue, Cost, and Profit A print shop makes bumper stickers for election campaigns. If $x$ stickers are ordered (where $x<10,000$ ), then the price per sticker is $0.15-0.000002 x$ dollars, and the total cost of producing the order is $0.095 x-0.0000005 x^{2}$ dollars. Use the fact that profit $=$ revenue $-$ cost to express $P(x),$ the profit on an order of $x$ stickers, as a difference of two functions of $x .$

Key Concepts

Cost Function

The cost function captures the total expense incurred in producing a given number of items. It typically includes both variable costs, which change with the production quantity, and fixed costs, which remain constant regardless of the number produced. In many problems, the cost function may be more complex than a simple linear expression, sometimes including quadratic or higher order terms to model factors such as economies of scale or production inefficiencies.

Profit Function

The profit function is defined as the difference between the revenue function and the cost function. It represents the net gain or loss from selling a certain number of items after all production costs have been considered. Analyzing the profit function allows businesses to determine optimal pricing and production levels, and to understand how changes in production scale affect overall profitability.

Revenue Function

The revenue function represents the total income generated from selling a certain number of items. In general, it is calculated by multiplying the number of units sold by the price per unit, and can be represented as a function of the quantity sold. This function is key to understanding how income scales with sales volume, particularly when the unit price might change with quantity due to discounts or pricing strategies.
