Let's calculate the 9.3% of the price of the television:
First, we need to convert 9.3% to decimal, to do that we divide the percentage by 100:

Now we can multiply the price of the tv by the percentage in decimal to get the amount of the tax:

The cost of the tax is $78.585, since the tax are values over the original price, we need to add the tax cost to the television cost:

The total price, with tax, is:
$923.58
