Zachary is starting a business selling handmade necklaces. he has
decided to invest an initial amount of $31 for advertising, and materials
cost 56 for each necklace he makes. zachary can sell his creations for
537 per necklace. once he makes and sells a certain number of
necklaces, he will break even, with identical expenses and sales. how
many necklaces would that take? what would the total expenses and
sales be then?
