Question 158783: A new fax machine was purchased for an office in HopeDale for $464.40 including tax. If the tax rate is 8 % , find the price of the fax machine before taxes.
I thought that I knew how to do this but my tutor says I am incorrect. Please help by telling me where I went wrong. Thanks !
8 % of 464.40 = 37.12
464.40 - 37.12 = 427.28

the $464.40 includes the tax __ if x is the price before tax, then 464.40 is 100% of x plus 8% of x

1.08x=464.40 __ dividing by 1.08 __ x=430

Let x = the price before taxes.
The price, including tax is $464.40:
The total cost of the fax machine can be expressed as:
x + 0.08x = $464.40 Simplify this and solve for x.
1.08x = $464.40 Divide both sides by 1.08
x = $430.00
Check:
The total price, including tax is:
$430 + 0.08($430) = $430 + $34.40 = $464.40
