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

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
