Formula Validation and Variable Isolation
A software quality assurance analyst is testing a reporting module that uses the formula to calculate growth rates. To ensure the module operates correctly, the analyst must identify the input value that would cause a system error and state the formula used to calculate the target variable directly. Based on the formula provided, what is the specific value of that must be restricted, and what is the final equation when solved for ?
