I don't understand this assignment.

Basically I think that I need to find some attribution models such as CPC( cost per click) or CPM ( cost por mille) As well as some ratios such as ROI and CTR( click through rate). Then I need to analyze both campaign with those ratios and attributions.

So, I have to analyze both campaign and explain it with formulas

Campaign A: showed advertising of the store making 1 million impressions, got 10,000 visits to the store, of which 250 made a purchase. Total income was 35,000 and the cost for each visit was 0.20

.

-Campaign B: released 100,000 impressions, but only got 5,000 visits. 150 made a purchase contributing a total income of 14,000. CPC was 0.22.
