Answer: The required cost of the TV is $497.9.
Step-by-step explanation: We are given to find the cost of a $459.95 LCD TV including sales tax rate of 8.25%.
The amount of sales tax is given by
[tex]S.T.\\\\=8.25\%\times459.95\\\\=\dfrac{8.25}{100}\times459.95\\\\=37.95.[/tex]
Therefore, the cost of the LCD TV with sales tax is
[tex]C.P.=459.95+S.T.=459.95+37.95=497.9.[/tex]
Thus, the required cost of the TV is $497.9.
