Challenge 4 - Spread yearly values across months

Challenge 4 - Spread yearly values across months

Your team created a summary of the total amount spent last year on each project. The data looks like the following:

Year Area Project exp
2022 area A proj A 120
2022 area B proj X 160

The finance department of your company, however, would like to have a more granular overview of the expenditures. In particular, the expenditures for projects in area A should be spread equally across 12 months, while those for projects in area B should be grouped by quarters. In the end, the above table should look like the following:

Year Area Project div exp
2022 area A proj A jan 10
2022 area A proj A feb 10
...
2022 area B proj X Q1 40
2022 area B proj X Q2 40
