The title of this thread has been edited from the original: Pricing items & tax

Is there anyway to price an item so that once tax is applied it totals up to an even amount? I am able to do it for most items but the following item will not work:

We want the amount charged to the customer, after tax is applied to equal $22.00. I put the amount in at $20.75, our tax is 6% or $1.24, and the total comes out to $21.99. If I increase the amount to $20.76 then add the 6% tax or $1.25 and the amount comes out to $22.01. Is there a fix for this?
