Final answer:
The question asks for the percentage increase in the price of fuel A per month, but without the specific original and new prices, it is impossible to accurately calculate the increase. The percentage increase formula is (New Price - Original Price) / Original Price × 100%.
Step-by-step explanation:
The student's question pertains to calculating the percentage increase in the price of fuel A per month. None of the provided options a) 2.96%, b) 4%, c) 4.08%, d) 104% directly answer this question with a clear related context. However, to calculate the percentage increase of an item over time, you can use the formula: (New Price - Original Price) / Original Price × 100%. Based on this, it seems there is some missing information that would be required to accurately calculate the percentage increase for fuel A.
For example, if the original price of fuel A was $2.00 per gallon and after a month the price increased to $2.08, the percentage increase would be calculated as follows: (($2.08 - $2.00) / $2.00) × 100% = 4%
Without the specific original and new price of fuel A, it is impossible to determine the exact percentage increase per month. Therefore, the correct response would be that we cannot determine the percentage increase without additional information.
