John commissions an artist to make him a 9 by 13 drawing. A black and white drawing that size would cost $160. He wants a color drawing so that is 50% more expensive. How much did he pay?

How much is the coloring? ** The extra cost for coloring is 160*.5=$<<160*.5=80>>80
How much did he pay? ** So the total cost was 160+80=$<<160+80=240>>240
