Final answer:
Without a clear pattern or additional context, it is not possible to determine the fixed utilities cost per month from the given numbers. The answer must be E. an amount other than those listed above, as none of the numbers provided match the potential answers listed.
Step-by-step explanation:
The student has asked for the fixed utilities cost per month. Looking at the provided numbers, one might attempt to find a consistent number across various months. However, without a context or a clear pattern in the figures provided, it's difficult to determine what exactly 'utilities cost' refers to and which numbers, if any, are relevant to the utilities cost.
Typically, when calculating fixed costs like utilities, one would look for a pattern or consistent figure that occurs repeatedly over different periods. If no such figure is consistent, we cannot reliably answer the question.
In this case, none of the numbers provided exactly match any of the potential answers (A to E), hence the answer must be E. an amount other than those listed above.
