Aboathouse costs $2500 a month to operate, and it spends $600 each
month for every boat that it docks. the boathouse charges a monthly fee of
$900 to dock a boat. if n is the number of boats, which equation represents
the profit function of the boathouse?

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

The boathouse charges $900/month for every boat docked. The revenue for n boats will be

The profit function can be constructed by subtracting revenue and cost

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
