Apartment rentals $A$ real estate company owns 218 efficiency apartments, which are fully occupied when the rent is 940 dollars per month. The company estimates that for each 25 dollars increase in rent, 5 apartments will become unoccupied. What rent should be charged in order to pay the monthly bills, which total 205,920 dollars ?

Key Concepts

Break-even Analysis

Break-even analysis is the process of determining the point at which total revenues equal total expenses, ensuring that there is no profit or loss. In this problem, it is used to find the rent level that exactly covers the monthly bills, linking revenue modeling with cost recovery.

Quadratic Equation Solving

When forming the revenue function by combining a linear price adjuster with a linear occupancy reduction, the resulting equation is quadratic. This concept encompasses the formulation, manipulation, and solution of quadratic equations, which is essential in determining the precise rent level required to meet the break-even point.

Revenue Modeling

This concept involves establishing a mathematical function that represents the total income generated by product sales or service usage, which in this case is computed as the product of the rent per apartment and the number of apartments occupied. It requires understanding how changes in price affect the total revenue and is fundamental in both business and economic modeling.

Linear Relationships

A linear relationship in this context refers to the predictable change in one variable as another variable changes by a constant amount. Here, each fixed increment in rent leads to a corresponding fixed reduction in the number of occupied apartments, establishing a straightforward linear connection between rent adjustments and occupancy.
