ASK YOUR TEACHER PRACTICE ANOTHER The demand x for a web camera is 25,000 unils per month when the price is $25 and 35,000 units when the price is $15. The initial investment is $275,000 and the cost per unit is $13. Assume that the demand is a linear function of the price. Find the prot P, in dollars, as a function of x. P(X) = Using the differential approximate the change in prot for a one-unit increase in sales when X = 23,000. dP = dollars Need Help
