Question

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?

Answer 1

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.
