Question

a firm is marketing a new cell phone. the firm determines that when it sells x units, the total revenue r(x), in dollars, is given by the polynomial function r(x)=100x - 0.2x^2. find an equivalent expression for r(x) by factoring out 0.2x. the equivalent expression is r(x)=□ (factor completely.)

Explanation:

Step1: Identify the polynomial

The given polynomial is $R(x)=100x - 0.2x^{2}$.

Step2: Factor out 0.2x

We can rewrite the polynomial as $R(x)=0.2x(500 - x)$.

Answer:

$0.2x(500 - x)$
