Apainter will paint n walls with the same size and shape in a building using a specific brand of paint. the painter's fee can be calculated by the expression nklh, where n is the number of walls, k is a constant with units of dollars per square foot, l is the length of each wall in feet, and h is the height of each wall in feet.

if the customer asks the painter to use a more expensive brand of paint, which of the factros in the expression would change?

K

Step-by-step explanation:

The factor that will change in the expression will be K.

n = number of walls

K = units of $/ft²

L = length of each wall in feet

h = height of each wall in feet

If the customer will request a more expensive brand of paint, the only factor that will change is K, because K holds the price of the paint over how many square feet.

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

hope this you
