11. An electronics-store manager knows that he will order up to $7,000 of
merchandise to restock his inventory.
He will order both computers and cell
phones. Each computer costs the store
$200, and each cell phone costs $100.
He can have in inventory a maximum of
45 cell phones and 30 computers. Each
computer is estimated to bring a profit
of $400. Each cell phone is estimated to
bring a profit of $100. How many com-
puters and cell phones should he pur-
chase to maximize profit? How much
money will the manager make if he sells
all the items purchased?
