An artist sells drawings. Each materials that he uses cost $30. He sells his drawings for $90. If he spends $600 for advertisement. How many drawings does he needs to sell?
I believe it is 10 since he in total makes 60$ a drawing because 90- the 30$ for the material. So 60$ in profit is 600/60 which is 10 so he would need 10 drawing I believe hope this helps!
