the figure on the right shows the graphs of the cost and revenue functions for a company that manufactures and sells small radios. more than how many radios must be produced and sold for the company to have a profit? the company needs to produce and sell more than radios to have a profit. (type a whole number.)
Answer
Explanation:
Step1: Recall profit - revenue - cost formula
Profit $P(x)=R(x)-C(x)$. The company makes a profit when $P(x)>0$, i.e., $R(x)>C(x)$.
Step2: Set up the inequality
We have $R(x) = 45x$ and $C(x)=10000 + 25x$. Set $R(x)>C(x)$: $45x>10000 + 25x$.
Step3: Solve the inequality for $x$
Subtract $25x$ from both sides: $45x-25x>10000+25x - 25x$. $20x>10000$. Divide both sides by 20: $x>\frac{10000}{20}$. $x > 500$.
Answer:
501
