A jewelry artist is selling necklaces at an art fair. It costs $135 to rent a booth at the fair. The cost of materials for each necklace is $4.50. The artist is selling the
necklaces at $12 each.
The equation 12n - 135 +4.50n represents the situation in which the artist
breaks even at the fair,
How many necklaces does the jewelry artist have to sell in order to break even?
