Based on the data below,which is the most effective advertising campaign?

The most effective advertising campaign can be determined by evaluating its return on investment(ROI),which measures the profitability of an investment relative to its cost.In this scenario,Campaign 1 emerges as the most effective because it has a greater return compared to Campaign 2.ROI is calculated by dividing the net profit generated from the campaign by the cost of the campaign,expressed as a percentage.Campaign1'sROIis20%($2,000profit/$10,000cost*100),whereas Campaign2's ROI is only 10%($1,000profit/$10,000cost*100).A higher ROI indicates that Campaign 1 yielded a better return relative to its cost,making it the more efficient and effective advertising investment.While Campaign 2 drove more leads,the ultimate measure of effectiveness lies in the campaign's ability to generate profitable outcomes,which is captured by the ROI metric.Therefore,Campaign 1 stands out as the most effective advertising campaign based on its superior return on investment.
