Question

A TV that usually sells for $175.95 is on sale for 20% off. If sales tax on the TV is 6%, what is the price of the TV, including tax?

Answer 1

Actual cost of the TV = $175.95
Percentage of discount given on the TV = 20%
Then
Amount of discount on the TV = (20/100) * 175.95 dollars
                                                 = 175.95/5 dollars
                                                 = 35.19 dollars
So cost of the TV after discount = (175.95 - 35.19) dollars
                                                    = 140.76 dollars
Now
Percentage of sales tax that needs to be added = 6%
Then
Amount of sales tax that needs to be added = (6/100) * 140.76 dollars
                                                                       = 844.56/100 dollars
                                                                       = 8.45 dollars
Then
Price of TV after adding sales tax = (140.76 + 8.45) dollars
                                                       = 149.21 dollars
So the cost of the TV after deducting the discount and adding the sales tax is $149.21
