ah ok, i see your point. i had worked out that P = $500 - 2xQ(10x20) as MC = MR (100=100), so price was 300 and output 20. the tax would mean a reduction in output to 15 units, by my calcs but how can i work out the corresponding price.

sorry, i understood that, but as the prices go up the output goes down. but how can you recalculate the price. output drops to 15 in an earlier question, but i cant get my head around working out the price
