question 29 (1 point) the revenue function for a product with demand function p(x)= - 5x + 42, where p is the price in dollars and x is the number of items in thousands is a) - 6x + 42 b) - 4x + 42 c) 1000(- 5x + 42) d) x(- 5x + 42)
Answer
Explanation:
Step1: Recall revenue formula
Revenue (R) is given by the product of the price (p) and the quantity (x). Here, the price - function is (p(x)=- 5x + 42) and the quantity is (x) (in thousands, but we first work with the general formula). So, (R(x)=x\times p(x))
Step2: Substitute price - function
Substitute (p(x)=-5x + 42) into the revenue formula. We get (R(x)=x(-5x + 42))
Answer:
d) (x(-5x + 42))
