Which two of the following use cases do you implement by using one or more...

Calculated fields are fields that derive their values from other fields or expressions. You can use calculated fields to implement use cases that require calculations based on user inputs or data sources, such as estimating costs, quoting prices, computing discounts, etc. For example, you can create a calculated field that multiplies the labor hours by the hourly rate to estimate the labor cost for painting a banquet hall, or a calculated field that adds up the premiums for different coverage options to quote the cost of an insurance policy.
