After a discount of 10%, the price of a jacket, including tax, is $70.79. The following equation can be used to find x, the price of the jacket without the discount.
x - 0.1x + 0.06(x - 0.1x) = 70.79

What is the price of the jacket without the discount

Answer 1

\[0.9x+0.06(0.9x)=70.79\]
\[0.9x+0.054x=70.79\]
\[0.954x=70.79\]
\[x=\frac {70.79}{0.954}\]
\[x=74.20\]
