an artist is going to an art fair. the artist will charge $20 for small prints $45 for large prints. the artist would like to sell twice as many small prints as large prints. the booth the artist is renting costs $510. how many of each size print must the artist sell in order to break even at the fair?
For each large print, he sells small prints. For the three prints, he makes 45+2*20=85$.
Rent = 510
He must sell 510/85=6 sets of three prints, or 6 large and 12 small prints to break even.
