I don't understand this assignment that well.

The assignment is basically to do an analysis of both campaigns. So, what I should do, is to see which formula is the best for each campaign. For example, see if the campaign needs a ROI, or CR or CTR, or to whether there are attribution models such as CPC, CPM, CPV, CPL or CPI.

ASSIGMENT:

A) showed store advertising with 1 million impressions, received 10,000 visits to the store, of which 250 made a purchase. The total income was 35,000 and the cost of each visit was 0.20

B )released 100,000 impressions, but only received 5,000 visits. 150 made a purchase with a total income of 14,000. The CPC was 0.22.
