This was a question on my exam. Please help me figure it out?

Question

A plasma t.v. costs 1875 dollars with tax. The tax rate is 7.5%. What is the price of the t.v. before the tax?

Answer 1

the orginal price (we'll use x) plus tax equals 1875. tax is 7.5%, so 1875=100+7.5%, or 107.5% so if you divide by 107.5 you will find 1%. you should get that 1%=17.4419 (rounded off), then to find 100% the total of the item you can times by 100, so you should get that the price without tax is $1744.19

hope this helps!

Answer 2

X is original price

$1875= X times 1.075
$1875/1.075 = X

$1744 = X

Answer 3

X x 1.075 = 1875 where X is the price before tax is added

1.075 means 100% plus 7.5%

X = 1875/1.075

Answer 4

multiply 1875 x 7.5%. Subtract the answer from 1875.
