A TV has a listed price of $510.99 before tax. If the sales tax rate is 8.25%, find the total cost of the TV with sales tax incl
Trava [24]

The most appropriate choice for sales tax will be given by-

Total cost of the TV with sales tax included  is $553.15

What is sales tax?

Sales tax is a tax imposed by the government on the price of a commodity for the sale of that commodity. Imposing sales tax on a product increases the price of the product. Nowadays, sales tax has been replaced by Goods and Service Tax (GST).

Here,

Listed price of television = $510.99

Rate of sales tax = 8.25%

Sales tax to be added = \frac{8.25}{100}\times 510.99

                                     = $42.16

Total cost of the TV with sales tax included = $(510.99 + 42.16)

                                                                        = $553.15
