Answer ($3.30 or three dollars and thirty cents)

I’ve never been taught this before but I hope I helped and got it right! (Sorry if I got it wrong) So what it says is the artist has 2 liters of paint for a project. So in 1 liter, there’s 1000 milliliters. So in 2 liters there’s 2000 milliliters in all. It says he ended off with 350 milliliters left, and each milliliter costs 2 cents. So what I did was, I subtracted 350 by 2000 (which is the milliliters) and got 1650. Next what I did was multiplied 0.2 to 1650, (the 0.2 is the cents) and got 330. Next what I did was 1650 divided 330 and got 5. Next what I did to try and check if I was correct was 5 times 330 and I got 1650. (I’ve never done this but I tried my best so sorry if I got it wrong but if I got it right you are welcome).

(Also the answer is 3.30 or three dollars and thirty cents)
