question 9 (1 point)\nthe 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\na) x(-5x + 42)\nb) 1000(-5x + 42)\nc) -6x + 42\nd) -4x + 42

Answer

Explanation:

Step1: Recall revenue formula

Revenue $R$ is the product of price $p$ and quantity $x$. Given $p(x)=- 5x + 42$ and quantity $x$ (in thousands), then $R(x)=x\cdot p(x)$.

Step2: Substitute price function

Substitute $p(x)=-5x + 42$ into the revenue - formula. We get $R(x)=x(-5x + 42)$.

Answer:

A. $x(-5x + 42)$
