sales tax chart
 

I know there must be a formula to figure this out easily, but I can't do it.
I am trying to make a chart like the illustration without figuring every
line.
{$9.50-$10.05=$.96(tax).} I have the formulas worked out to $100, but I am
needing to eliminate the exta lines one by one to create the x-x part.
Isn't there someway to do this? Thanks!
