Final answer:
To determine Melea and Nate's babysitting charges, one must examine the provided table and graph to identify the one-time fee and the hourly rate, similar to how Svetlana's tutoring charges are calculated using the linear equation y = 25 + 15x.
Step-by-step explanation:
You have posed a question relating to the determination of charges for babysitting services provided by Melea and Nate. Without the specific data from the provided table and graph, it is not possible to give an exact figure. However, I can guide you on how to calculate it based on an example.
Let's consider a similar scenario with Svetlana, who tutors to make extra money. Svetlana charges a one-time fee plus an hourly rate. The linear equation representing her earnings per session is y = 25 + 15x, where 'y' is the total amount she earns and 'x' is the number of hours she tutors. Here, the one-time fee is $25, and the hourly rate is $15. This information allows us to determine how much Svetlana charges for each tutoring session.
In the case of Melea and Nate, the approach will be similar. You will look at the linear relationship between the hours they babysit and the total earnings to identify the one-time fee and the hourly rate they charge. This can be done by examining the provided table and graph to see how their earnings change with the number of hours they work.
