Final answer:
The percent change for Year 2 compared to the base year (Year 1) is -4.0%.
Step-by-step explanation:
The percent change for Year 2 compared to the base year (Year 1) can be calculated using the formula:
Percent change = [(Year 2 sales - Year 1 sales) / Year 1 sales] * 100%.
Plugging in the values, we get:
Percent change = [($380,160 - $396,000) / $396,000] * 100%.
Simplifying the equation, we get:
Percent change = (-$15,840 / $396,000) * 100%.
Percent change = -4.0%.
Therefore, the percent change for Year 2 compared to the base year is -4.0% (option c).
