I need the answer to this question.

Until recently, hamburgers at the city sports arena cost $2.50 each. The food concessionaire sold an average of 1,750 hamburgers on game night. When the price was raised to $3.00, hamburger sales dropped off to an average of 1,500 per night. The concessionaire's fixed costs were $3, 139.20 per night and the variable cost was $0.20 per hamburger. Answer the following questions (A) through (F). (A) Assume that the relationship between price p and demand x is linear. Express p as a function of x and find the domain of this function. P =0 The domain of p is . (Type a compound inequality.) (B) Find the revenue function in terms of x and state its domain. R(x) = The domain of R(x) is (Type a compound inequality.) (C) Assume that the cost function is linear. Express the cost function in terms of X. C(x) = (D) Graph the cost function and the revenue function in the same coordinate system. Choose the correct graph below. O A. O B. OC. OD.
