You are on a prom decorating committee and are
in charge of buying balloons. You want to use
both latex and Mylar balloons. The latex
balloons cost 0.10 each and the Mylar balloons
cost 0.50 each. You need 125 balloons and you
have 32.50 to spend. How many of each can you
buy? Write both equations, graph it and answer
the question in a short sentence.
