Answer
the company loses $4,000$ dollars when producing and selling 300 radios.
Work Step by Step
Given the formulas $R(x)=50x$ and $C(x)=10000+30x$, we have
$R(300)-C(300)=50(300)-(10000+30(300))=15,000-10,000-9,000=-4,000$
This means that the company loses $4,000$ dollars when they produce and sell 300 radios.
