Alex knits hats and
scarves to sell at an art fair. he can make at
most 20 hats and 30 scarves, but no more than
40 items altogether, in time for the art fair.
write and graph a system of inequalities that
shows the possible numbers of hats and scarves
alex can bring to the art fair if he wants to
bring at least 25 items. how do the solutions
change if he wants to make more hats than
scarves? explain.
