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?

Step-by-step explanation:

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!

step-by-step explanation:

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn
