Cost of the video game bought by James = 49.99 Cost of the controller bought by James = 34.95 Cost of the walk through manual bought by James = 19.99 Percentage of sales tax in the area of James = 8.25% Total amount spent by James for buying the goods = 49.99 + 34.95 + 19.99 = 104.93 Amount of sales tax = (8.25/100) * 104.93 = 865.67/100 = 8.66 So the total amount paid by James including tax = 104.93 + 8.66 = 113.59 So the total cost of the purchase made by James is 113.59. I hope the procedure is clear enough for you to understand.
