Final answer:
The mathematical equation representing the total cost for a participant in Beverly's Zumba classes is y = 20 + 5x, where x is the number of classes attended.
Step-by-step explanation:
Considering Beverly's Zumba classes and the associated costs, we can formulate an equation similar to the examples provided. In Svetlana's case, she charges a fixed fee plus an additional rate per hour. For Beverly's classes, the equation would represent the total cost for each individual, considering the one-time equipment fee of $20 plus $5 per class she attends.
The total cost (y) for each participant who attends x number of classes can be represented by the linear equation y = 20 + 5x. This equation captures the initial equipment fee (fixed cost) as well as the variable cost per class. This kind of cost analysis is important in businesses like the Yoga Center example, where knowing the fixed costs like space rental and variable costs like hiring instructors helps in financial planning and decision making.
