Answer 2

Calculating Increase in Demand After Advertising Campaign

To calculate the percentage increase in demand after the advertising campaign, we can use the following formula:

Percentage Increase = ((New Demand - Old Demand) / Old Demand) * 100

Given that the demand increased by 4 times, we can use this information to calculate the percentage increase.

Calculation

Using the formula: Percentage Increase = ((4 - 1) / 1) * 100 = 300%

Therefore, the demand for the product increased by 300% after the advertising campaign.

This calculation is based on the fact that the demand increased by 4 times, which corresponds to a 300% increase in demand.

I hope this helps! If you have any other questions or need further clarification, feel free to ask.
