OpenStudy (ciarán95):
With a sales tax of 7%, we are adding on 7% of the selling price of the laptop to find its total cost. So, 100% (selling price) = $850 1% of the selling price = $850/100 = $8.50 107% of the selling price ($850 + sales tax) = $8.50 x 107 = $909.50 (C.)
OpenStudy (texaschic101):
or 850 + 850(.07) = your total cost
