A hospital spends $364,468 per year (52 weeks) on electricity. On average, how much does it spend per week on electricity?

Rationale

The hospital spends $7,009 per week on electricity.

This value is obtained by dividing the total annual expenditure of $364,468 by the total number of weeks in a year, which is 52.

A ($7,090) YOUR ANSWER

This is incorrect. It seems to be a transposition of the correct number, $7,009. It is important to pay close attention to the order of digits when performing calculations.

C ($709) YOUR ANSWER

This is incorrect. It is significantly less than the correct value of $7,009. This amount would only total to $36,868 over a year, which is far less than the annual cost of $364,468.

D ($79) YOUR ANSWER

This is incorrect. It is far less than the correct answer of $7,009. If the hospital only spent $79 per week on electricity, the total annual cost would only be $4,108, which is significantly less than the actual annual cost of $364,468.

Conclusion

In problems involving division to calculate averages, it is important to perform the division correctly and ensure the digits are in the correct order. The correct answer, $7,009, is the result of dividing the total annual cost of $364,468 by 52 weeks. The other choices represent common errors such as transposing digits or significantly underestimating the amount.
