I don't understand this assigment.

I need to add ratio like ROI, CR, CTR or CPC. CPM and others.

ASSIGMENT:

There have been 2 campaigns, do an analysis of both and choose the best one for the client.

Campaign 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

Campaign 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.
