John bought chairs for his office. The original price for the chairs was $45 EACH, but they had been marked down by 30 percent. How much did John pay for 10 chairs?

Answer 1

The chairs had been marked down by 30 percent, so the new price for each chair is 45 - (30/100) * 45 = $31.50.
John bought 10 chairs, so he paid a total of 10 * $31.50 = $<<10*31.50=315>>315. Answer: \boxed{315}.
