Excel - Simple task.

Job ID: 37537692

Budget: $10 – $15 USD

I have a table with hundreds of entries.

I need to add .03, 04 or .05 cents to certain columns.

So it will turn the amount from .16 to .19, .20, or .21

It is tedious to go thru hundreds of cells to do this. Is there a way to do it with a formula?
