I need to update an excel formula

Just like last question, except instead of adding to the date in coumn V, I need it to subtract the total days from it i.e., 14 + X number of days

Here is the original post:

I need an excel formula to look at the value of certain cells.

1. If the Length of the value in column V is less than or equal to 1500, then the length needs to be divided by 175. In the attached example this would be V2/175=5.7 days (6 days).

2. Take the answer from number 1 (6 days)and add 14 more days to the value in column I. These only need to be Network Days, not counting Saturday or Sundays

3. If the Length of the value in column V is greater than 1500, then the length needs to be divided by 300. In the attached example this would be V3/300=5 days (5 days).

4. Take the answer from number 3 (4 days) and add 14 more days to the value in column I. These only need to be Network Days, not counting Saturday or Sundays

5. If day ends up being a fraction, 4.32 days, round up to 5 days.
