Answer

Explanation:

Step1: Recall revenue formula

Revenue is the product of the selling - price per unit and the number of units sold.

Step2: Identify selling - price and number of units

The selling price per box of cereal is $4.12 and the number of boxes sold is $x$.

Step3: Write the revenue function

The revenue function $r(x)$ is given by $r(x)=4.12x$ (the fixed costs and production costs per unit are not relevant for the revenue function; revenue only depends on the selling price and the quantity sold).

Answer:

D. $r(x) = 4.12x$
