An electronic company sells two kinds of speakers, the Tweeter and the Boomer,manufacturing at most 140 speakers each week. Each Tweeter takes 6 hours to build, andeach Boomer takes 12 hours. Each week, they hire workers for at most 960 hours. Theygain $56 in profit for each Tweeter the make, and $63 profit for each Boomer they make.How many of each speaker should they make to maximize profit?Say what your variables represent in words.
