clicks = budget/CPC

All numbers are randomised.

Given a campaign budget and a CPM, calculate the number of impressions.

Calculate CTR given number of clicks and number of impressions served.

percentage CTR is 0.5, 1, 1.5 or 2%. Number of impressions is randomised.

Given budget and number of sales, calculate the cost per acquisition (CPA)

n = 1, 1000, 10000, or 100000.
