For the following exercises, set up the augmented matrix that describes the situation, and solve for the desired solution. A major appliance store is considering purchasing vacuums from a small manufacturer. The store would be able to purchase the vacuums for \$86 each, with a delivery fee of \$9,200, regardless of how many vacuums are sold. If the store needs to start seeing a profit after 230 units are sold, how much should they charge for the vacuums?

Key Concepts

Augmented Matrix

An augmented matrix is a compact form of representing a system of linear equations. It includes both the coefficients of the variables and the constants from the right-hand side of the equations in a single matrix, which is then manipulated using row operations to find the solution set.

System of Linear Equations

A system of linear equations consists of two or more linear equations involving the same set of variables. These systems are used to model relationships between quantities and can be solved using methods such as substitution, elimination, or matrix techniques.

Break-even Analysis

Break-even analysis is a financial calculation to determine the point at which total revenues equal total costs. This concept is used to pinpoint the number of units that must be sold or the price at which a product must be sold to achieve no loss or profit, making it a critical tool in decision-making and pricing strategies.

Cost and Revenue Functions

Cost and revenue functions model the expenses incurred and income earned by a business. The cost function often includes a fixed component and a variable component that depends on the number of units produced or sold, while the revenue function is typically expressed as the product of the selling price and the number of units sold. Setting these functions equal is a common method to analyzing when a business will begin to make a profit.
