A boathouse costs $2200 a month to operate, and it spends $550 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 the boathouse?

A. p=300n-2200

B. p=850n-2200

C. p=300n+2200

D. p=2200n+300

Answer A:  300 n - 2200

Step-by-step explanation:

The profit function will be the income  minus the cost of maintaining the boathouse.

The income comes from the number of boats that it docks (n) , times the monthly fee that each boat pays ($850), That is:

Income = 850 n

Now the monthly cost to operate the boathouse is the fix $2200 cost plus $550 per boat. That is:

2200 + 550 n

Now, the difference "Income - Cost" that defines the profit function becomes:

850 n - {2200 + 550 n} = 850 n - 550 n - 2200 = 300 n - 2200

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
