How much does the canvas cost? ** Maria wants to pay 3 * 20 = $<<3*20=60>>60 for the canvas.
How much does the paint cost? ** Maria needs 5 liters of paint, so the cost of it would be 8 * 5 = $<<8*5=40>>40.
How much money will Maria earn on the painting? ** So in total Maria will earn 200 - 40 - 60 - 20 = $<<200-40-60-20=80>>80 if she will be able to sell the painting at the mentioned price.
