Or take the price multiply by .085. That gives you your tax. Just add that on to the original price of the video card. It's the same as Monger's up there. I just converted the 8.5 to decimal percent already

Ex.

1) Price= $95.00 Tax= 8.5%

2) $95x.085= $8.075

3) $8.075+$95.00= $103.08 (rounded to the nearest hundreths)
