Cost function. A small manufacturing company produces two models of a surfboard: a standard model and a competition model. If the standard model is produced at a variable cost of $210 each and the competition model at a variable cost of $300 each, and if the total fixed costs per month are $6,000. then the monthly cost function is given by C ( x , y ) = 6 , 600 + 210 x + 300 y where x and y are the numbers of standard and competition models produced per month, respectively. Find C (20, 10), C (50, 5), and C (30, 30).
