Performance report using the flexible budget

The Antigua Blood Bank, a private charity partly supported by government grants, is located on the caribbean island of antigua. The blood bank has just finished its operations for september, which was a particularly busy month due to a powerful hurricane that hit neighboring islands causing many injuries. The hurricane largely bypassed Antigua, but residents of Antigua willingly donated their blood to help people on other islands. As a consequence, the blood bank collected and processed over 10% more blodd than had been origially planned ofr the month. A report prepared by a government official comparing actual costs to budgeted costs for the blood bank appears below. continued support from the fovernment depends on the blood bank;s ability to demonstrate control over its costs.

The managing director of the blood bank was very unhappy with this report, claiming that his costs were higher than expected due to the emergency on the nieghboring islandfs. He also pointed out that the additional costs had been fully covered by payments from hrateful recipients on the other islands. The governments official who prepared the countered that all of the figures had been submitted by the blood bank to the government; he was just pointing out that actual costs were a lot higher than promised in the budget.

Required:
1. Prepare a new performance report for September using the flexible budget approach. (Note: Even through though some of these costs might be classified as direct costs rather than as overhead, the flexible budget approach can still be used to prepare a flexible budget performance report.)
2. Do you think any of the variances in the report you prepared should be investigated? Why?

Type of help I am looking for.
I have done the problem and am not sure if I have completed all elements of the performance sheet correctly. I want to confirm that all elements are correct. Please show step by step how to complete the performance report using the flexible budget approach.
