Mark purchases a new television that is on sale for 40% off of the regular retail price. if the retail price is $679, what is the final cost including a 7% sales tax? round your answer to the nearest cent. $290.61 $319.13 $435.92 $454.93

We are given retail price of the new television as $679.

There is 40% off on the regular retail price .

So let us find the price after 40 % off.

New price after discount = 40% of retail price= 40% of 679

40% of 679 = 0.4 *679 = $271.6

So price of television after discount is $271.6

Now there is 7% sales tax to be included in this.

So first we find 7% of 271.6 which is 19.012.

Final price = New price + 7% sales tax price

Final price of television = $271.6 + $19.012 = $290.612

Final cost of television is 290.61 dollars. First option is the correct choice.
