Study the flow given in the following diagram and answer the questions that follow.  Q 21.   What number is stored in Box 1 at the end of the flowchart?

To answer your question accurately, I would need to view the specific flowchart you're referencing. Since I can't see images or diagrams, I can provide guidance on how to interpret flowcharts.

Step 1: Analyze the Flowchart

1. Identify the starting point of the process in the flowchart.
2. Follow the arrows to understand the flow of operations and how values are processed.
3. Take note of any operations (like additions, subtractions, assignments, etc.) that occur along the path leading to Box 1.

Step 2: Identify the Operations

1. Make a list of all operations affecting the value in Box 1.
2. Carefully note any conditions or loops that could lead to variations in the outcome.

Step 3: Compute the Final Value

1. Tally the operations sequentially to see how they affect the value destined for Box 1.
2. Look for any checks (if-else statements) that might change the expected outcome.

Step 4: Conclusion

1. After following through the entire flowchart, summarize the operations that specifically led to the final value in Box 1.

If you can describe the flowchart or provide the operations mentioned within it, I would be more than happy to assist you further!
