We calculate the cost per click in advertising, but how would you solve the problem?

Question

Mathematics

Given:
Application price: 500 rubles
Number of applications: 3 applications
Spent on all applications: 1500 rubles
Average CPC: 35 rubles It is
necessary to calculate the recommended CLICK COST so that the price of the APPLICATION is 249 rubles.
Please tell me how would you solve this problem?

Answer 1

In total, 1500 were spent, the average cost per click: 35
1500 / 35 = 42 clicks if rounded according to the rounding rules.
42 clicks brought 3 requests for 500 rubles, which means that 1 request can be received from 14 clicks (42 / 3).
The application should cost 249 rubles and we need 14 clicks if we accept that the conversion from changing the price will not change, then 249/14 = 17.78 recommended CPC.
