Answer
A)$\$105,000$
B)$\$115,000$
C) $\$8$
D) The revenue decreases for prices greater than $\textbf{price}>\$ 8$.
Work Step by Step
A) The graph shows that at a price of $\$ 4$, the revenue would be $\$ 105,000$.
B) The graph shows that the maximum revenue per month is $\$115,000$.
C) From the graph, we see that the price that gives maximum revenue is $\$ 8$.
D) The graph is decreasing to zero right after the vertex of $(8,115,000)$. This means that the revenue is decreasing for all prices higher than $\$8$. This can be expressed as $\textbf{price}>\$ 8$.
