A toy manufacturer makes miniature trucks. The price p (in dollar) and the demand x (number of miniature trucks) are related by the equation 6000 − 600p = x. The total cost for the same toy manufacturer to produce x miniature trucks can be modeled by C(x) = 8x + 450. (a) Express the price p in terms of the demand x. Find the revenue R(x) if the manufacturer sells x miniature trucks in a month and find the domain of this function. (b) Graph the cost and revenue functions on the same coordinate system for 0 ≤ x ≤ 6000. (c)  What is the minimum number of trucks the toy manufacturer must sell to break even? (d) Find P' (300) and interpret the result. (e) What is the exact profit from the sale of the 301st miniature truck?

Question

A toy manufacturer makes miniature trucks. The price p (in dollar) and the demand x (number of miniature trucks) are related by the equation 6000 − 600p = x. The total cost for the same toy manufacturer to produce x miniature trucks can be modeled by C(x) = 8x + 450.
(a) Express the price p in terms of the demand x. Find the revenue R(x) if the manufacturer sells x miniature trucks in a month and find the domain of this function.
(b) Graph the cost and revenue functions on the same coordinate system for 0 ≤ x ≤ 6000.
(c)  What is the minimum number of trucks the toy manufacturer must sell to break even?
(d) Find P' (300) and interpret the result.
(e) What is the exact profit from the sale of the 301st miniature truck?
