A

Step-by-step explanation:

Assume Alexandra has already recorded 2 months.

First month:

Fix: 1832.76

total: 1832.76

Last month:

Fix:1832.76

total: 4295.82

Therefore, variable expense of last month is

4295.82-3665.52, oh no! we don't have the answer.

This contradict with our assume.

Assume Alexandra has already recorded 1 month.

Last month:

Fix:1832.76

total:4295.82

Variable = 4295.82 - 1832.76 = A
