1. The problem is to understand where the value $FC=14$ comes from. 2. Typically, $FC$ could represent a fixed cost, force constant, or another variable depending on the context. 3. To find $FC=14$, you need to check the problem statement or given data where $FC$ is defined or calculated. 4. If $FC$ is a fixed cost, it might be given directly as $14$ units. 5. If $FC$ is calculated, it could come from an equation or measurement provided earlier. 6. Without additional context, $FC=14$ is likely a given constant or a result from a previous step. 7. Always refer back to the original problem or data source to verify such values. Final answer: $FC=14$ is either a given constant or derived from prior information in the problem.
