so you are applying a discount on C7 if its over 65,000 in your example formula
your first question says 10% if greater than 20,000
and now you say if less than 30,000 there is no discount
so they do not really work out
Lets say you wanted to apply a discount and show the actual discounted price in a cell
so A1 = calculated price
and A2 = The Price with or without a discount
and a 10% discount applies for anything over 30,000
to actually calculate the new value
=IF(A1>30,000, A1*0.9, A1)
this applies a 10% discount to the value by * 90% and now shows the price you are to pay
if you just want the cell to show a % value
=IF(A1>30,000, A1*0.1, 0)
this will now show 10% of the value in the cell and if no discount applies shows 0
does that help?
