Refer to Problem 19–5A and add the following requirement.

Prepare a letter to the president of the company, Sue Tombert, describing the changes you made. Explain clearly why net income is different after the changes. Keep the following points in mind as you compose your letter.

1. This is a letter to the president of a company, who is your friend. The style should be generally formal, but you may relax some requirements. For example, you may call the president by her first name.

2. Executives are very busy. Your letter should tell the president your main results first (for example, the amount of net income).

3. You should include brief explanations so that the president can understand the changes you made in the calculations.
