I am working on budget variance. Here is the question below. I am not sure I understand what it is asking for. everything in bold is my answer to the problem. I have checked my math so I know my calculations are correct but I am unsure how to answer this question.

1. Your friend quickly points out that the laundry provided a greater volume of services (cleaned more pounds of laundry) than expected in the original budget. How much of the total expense variance can be explained by the fact that the laundry produced more output than budgeted?

If they had produced the predicted volume of laundry at the predicted cost = $13,000

If they had produced the actual volume at the actual price = $16,512.34

If they had produced the predicted volume at the actual cost = $13,987.5

If they had produced the actual volume at the predicted cost = $15,275.2
