K is the only factor that will change if the customer asks for a more expensive brand of paint.
The correct option is C.
The figures used to represent geometric shapes in mathematics are those that show how commonplace items are shaped. Shapes are the outlines of objects in geometry that have surfaces, angles, and boundary lines.
n = number of walls
K = units of $/ft²
L = length of each wall in feet
h = height of each wall in feet
This equation shows that A and h will be used to determine the area of each wall.
The variable n is the number of walls,
n times the area of the walls will give the amount of area that will need to be painted.
The only remaining variable is K.
This represents the cost per square foot and is determined by the painter’s time and the price of paint.
