You are thinking about purchasing a new 55-inch T. V. at Walmart. The sales price on the T. V. is $425. If the sales tax is 7.25%. How much would the T. V. cost?

$455.81
I found this because when you are adding a sales tax you add it to the sales price. So you take the price the store is selling what you are buying. This would be the T.V, which is being sold at $425 and add the 7.25% tax. You can just put that into a calculator and get 455.8125. Take the 25 away. $455.81.
