Answer:
[tex]P(n)=300n-2500[/tex]
Step-by-step explanation:
The fixed cost to operate the boathouse is $2500/month. It also has a cost of $600/month for every boat it docks.
If n boats are docked, then the total monthly cost is expressed as
[tex]C=2500+600n[/tex]
The boathouse charges $900/month for every boat docked. The revenue for n boats will be
[tex]R=900n[/tex]
The profit function can be constructed by subtracting revenue and cost
[tex]P(n)=900n-(2500+600n)=300n-2500[/tex]
