Business case using cumulative gains curve

The cumulative gains graph can be used to estimate how many donors one should address to make a certain profit. Indeed, the cumulative gains graph shows which percentage of all targets is reached when addressing a certain percentage of the population. If one knows the reward of a campaign, it follows easily how many donors should be targeted to reach a certain profit.

In this exercise, you will calculate how many donors you should address to obtain a 30 000 Euro profit.

Plot the cumulative gains curve. The predictions are in predictions_test and the true target values are in targets_test.
Assume the cost of a campaign is 0 Euro and the reward of addressing a target is 50 Euro. Fill out how many targets should be reached to make 30 000 Euro profit.
There are 1000 targets in total. Fill out which percentage of the targets should be addressed.
Use the cumulative gains curve to know which percentage of the population should be addressed. Round to the tenth.
Given that the population consists of 10 000 donors, fill out how many donors should be addressed.
