A $800 tv is on sale for 40% off. What is the sale price? What is the final price after paying 6% tax?

Sale price is $480

Final Price is $508.80

Step-by-step explanation:

$ saved = Original Price x Discount % / 100

S = 800 x 40/100

S = 32000 / 100

S = $320

Subtract 320 from 800 and get $480.

Multiply $480 by 0.06 to get $28.80 then add $28.80 to $480 to get $508.80

0.40 x $800 = $320

$800 - $320 = $480

$480 x 0.06 = $28.80

$480 + $28.80 = $508.80
