20 (3 points) A music store is selling posters and CDs. Each poster gives a profit of $3.00 and each CD
gives a profit of $5.00. The store needs to make an
average profit of at least $200 per hour to stay in
business. The store can sell no more than 40 posters
and no more than 70 CDs in any given hour
because of supply constraints. Let x represent the
number of posters sold and y represent the number
of CDs sold. Write and graph a system of
inequalities showing how many of each item
(posters and CDs) the store needs to sell per hour to
make a sufficient profit.
