TV for $500 and the tax is 5.5 what is the original price of the TV
crimeas [40]

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
