I was given this question and was provided the answer. Wondering how he came up with it. Please and thank you.

Ultratech Company's headquarters are a "campus" in the outskirts of San Francisco, California. For the convenience of its employees and to help preserve the environment, the company operates a motor pool of buses running between points in San Francisco and the company's Campus. The motor pool operated with 20 vehicles until February, when an additional bus was acquired and put in service. The motor pool furnishes gasoline, oil, and other supplies for its buses. A mechanic does routine maintenance and minor repairs. Major repairs are performed at a nearby commercial garage. Each year, the supervisor of the motor pool prepares an annual budget, which is reviewed by the company's management and approved after suitable modifications. The following cost control report shows actual operating costs for March of the current year compared to one- twelfth of the annual budget. Ultratech Co.

The supervisor of the motor pool, Ralph Kramden, is unhappy with the report, claiming it paints an unfair picture of the motor pool's performance. He has asked for your help preparing for a meeting with management in which he believes his performance will be criticized as a result of the variances shown in the Cost Control Report.Prepare a memo to Ralph Kramden, including the following: 1. Explain some reason why although accurate, the Cost Control Report may not be an effective performance evaluation tool. 2. Explain what a flexible budget is, how it differs from the one used in the report and what the advantages of a flexible budget are. 3. Prepare a new performance report for March based on a flexible budget that shows spending variances. 4. Analyze the motor pool's performance based on your flexible budget. 5. Explain the deficiencies in the original cost control report and how the report that you prepared based on a flexible budget overcomes these deficiencies
