John bought chairs for his office. The original price for the chairs was $42.95 each, but they had been marked down by 33 percent. How much did John pay for 8 chairs?

Each chair was marked down by 33/100 * $42.95 = $<<33/100*42.95=14.1685>>14.1685.

So each chair cost $42.95 - $14.1685 = $<<42.95-14.1685=28.7815>>28.7815.
Thus, John paid a total of $28.7815 * 8 = $<<28.7815*8=230.252>>230.252 for the chairs. Answer: \boxed{230.25}.
