Formula to generate $ amount of another cell

Excel Noob here, I need help with formula that generates a dollar amount based on another cell using a percentage. I do not want end result to be a percentage.

Ex: person A has a salary of $100,000 and works on 3 projects at a 40-30-30 split

Desired result is 3 cells that contains dollar amounts based on these percentages.

I am using excel on windows 11 - Microsoft Office 365
