bookRevenue Calculation

As we have previously mentioned, using variables can streamline the process of working with data by allowing for clear, concise, and efficient calculations. Now, let's apply our variables to a practical example.

Tarefa

Continuing with the exercise from the previous chapter, we can calculate the projected revenue over a 4-year period using variables. Here's how:

  1. To determine the anticipated revenue after 4 years, use the variables initial_money, interest_rate, and n_years. Store the result in the revenue variable.
  2. Display the calculated revenue in the following format:

The formula for revenue is: initial_money * (1 + interest_rate / 100) ^ n_years.
