Answer:
(since there is no percentage given i will provide two alternate answers one including percentage and one exclusive of percentage)
cost of TV inclusive of tax = $500
we first multiply the tax with total amount
$500 * 5.5
= $500 * 55/10
=$500 * 11/2
= $250 * 11
=$2750
original price of TV = $2750
alternate answer assuming there is a percentage sign with 5.5
the amount of tax on TV is 5.5%
we first multiply the percentage of tax with total amount
$500 * 5.5/100
=$27.5
original price of TV = $500 - $27.5
= $472.5
