Olivia makes and sells bracelets and necklaces. She can make up to 60 pieces per week, but she can only makeup to 40 bracelets and 40 necklaces. Write and graph a system of inequalities that shows the combination of bracelets and
necklaces that she can make if she wants to sell at least 30 items per week. If necklaces sell for $80 each and
bracelets sell for $5 each, what is the most money she can make in a week? Explain.
