James buys a video game for his xbox for 49.99 a controller for 34.95 and a walk through manual for 19.99 the sales tax in his area is 8.25% what will be the total cost of his purchase

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.
