If I purchased something and the total cost was $117.15 including tax, what would I multiply $117.15 by to see how much I paid in sales tax, if the sales tax was .065% (6 1/2 percent)?

(answer subject to the accuracy of my cheapo calculator) 0.146393512 derived as follows 117.15 / 1.065 (1 plus the tax rate) = 110 (the untaxed principle) 117.15 - 110 - 17.15 (the tax) 117.15 / 17.15 = 6.83090379 Taking the reciprocal of this answer 1 / 6.83090379 = 0.146393512 test: 117.15 X 0.146393512 = 17.14999999 (approximately the taxed amount) Jul 12 05, 8:39 AM
