Is Our Project Profitable? ROI 1/2

Is our project profitable? To figure this out, you can calculate one simple metric titled ROI; the formula is:

roi

Earnings, the sum of the column 'money_spent'.
Losses, the sum of the column 'cost'.

Завдання

Calculate the sum of the column df['cost'], and assign it to the variable cost_sum.
Calculate the sum of the column df['money_spent'], and assign it to the variable spent_sum.
Calculate ROI:

Subtract cost_sum from the spent_sum.
Divide the subtraction by the cost_sum.

Output the ROI.

The result was already multiplied by 100 to get it in percentage.
