This is my very first post. I am a bit nervous because I am unsure if
I am creating this post correctly. Anyways, I need help on a formula
that will do the following:

Lets say that there are 100 Total Lunch days. As part of the 100 Total
Lunch days, there are 10 Sandwich days.

The Sandwich day rate is currently 10%.

The new target Sandwich day rate is 4.3%.

To match the new target Sandwich day rate, I need to figure out the NEW
Total Lunch days and the NEW Sandwich days.
Sandwich Days/Total Lunch days would be 4.3%.

What formula would I use to do this?
I am using excel.

Thanks.

Well you created the post just fine, but I'm a little confused
on what you are trying to do. You need to know either the number
of total lunch days or the number of Sandwich days. You can't solve
for both. Do you know the total lunch days?
