In Ontario, including GST and PST there is a total of 15 percent tax on each purchase. If John bought a stereo in Ontario for a total of $320.85 including tax, what was the price ofnthe stereo without tax

since tax is added to 320.85
so price without tax is x
so
x+15x/100=320.85
100x+15x=32085
115x=32085
x=32085/115=279
