Boathouse costs $2750 a month to operate and it spend $600 each month for every boat that it docks. The boathouse charges a monthly fee of $850 to dock a boat. If n is the number of boats. Which equation represents the profit function of boathouse?
A.P=2750n+250
b.p=600n + 2750
c.p=850n + 2750
d.p=250n -2750
A.P=2750n+250
b.p=600n + 2750
c.p=850n + 2750
d.p=250n -2750

Only D works. All the others have obvious flaws.
Since net profit from each boat is $850 − $600 = $250, and the operations cost is $2750, then $250 times n (that is, from each boat) is what it earns, and it has to spend out $2750 a month.
