There are several ways and this is probably the simplest

Put the purchase price in a1
Put this formula in b1
=IF(C1="","",A1/C1)

enter different numbers in c1 to get the amount depending on partners.

I am buying a new business with partners. The cost is $386,450. We may have
up to 10 partners, so each would contribute $38,645. I would like to build a
table that allows "what if" scenario. For example if we only get 8 partners
how much do the 8 need to contribute, or 6, 9, 7 and so on. How can I develop
a formula that will allow me add to remove partner contribution levels and
still keeping the total amount $386,450? I would like to do this real time
during a presentation with the partners present.
