Brandon buys a television set for $1342.30, including sales tax. If the sales tax rate is 8.25% tax, then what is the cost of the set before tax? How much tax did he pay?

Answer 1

We assume the cost of the set before tax is X dollars,

then 0.0825X will be the tax cost,

the total price for the TV set will be X + 0.0825X, that is, 1342.30 dollars

express it in equation will be

X + 0.0825X = 1342.30

1.0825X = 1342.30

X = 1240

then 0.0825X = 0.0825 * 1240 = 102.3

The cost of the set before tax is $1240 and the $102.3 tax he paid

Answer 2

Pretax price was $1240. Post tax $1342.30

subtract to get tax of $102.30

1342.30 = 1.0825x where x is the pretax price

divide 1342.30 by 1.0825 to get 1240
