Cost Functions for a Loudspeaker System Acrosonic manufactures a bookshelf loudspeaker system that may be bought fully assembled or in a kit. The costs in labor and material incurred in manufacturing a fully assembled system and a kit are $210 and $150, respectively. In addition, Acrosonic has fixed costs of $20,000/month. (a) Write the monthly cost function C for Acrosonic in terms of the number of fully assembled systems x and the number of kits y manufactured $C(x, y) =$ (b) What is the domain of C? The domain of C is the set of all x and y such that $x + y < 20,000$. The domain of C is the set of all x and y such that $x < 150$ and $y < 210$. The domain of C is the set of all x and y such that $x < 210$ and $y < 150$. The domain of C is the set of all x and y such that $x > 210$ and $y > 150$. The domain of C is the set of all x and y such that $x \ge 0$ and $y \ge 0$. (c) What is the total cost (in dollars) incurred in manufacturing 1,000 fully assembled systems and 200 kits in a month?
