Question

A painter 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 nKeh, 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.

Answer 2

Answer:

The painter’s fee is given by nKAh where n is the number of walls, K is a constant with units of dollars per square foot, A is the length of each wall in feet, and h is the height of each wall in feet.

Examining 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, so 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, which represents the cost per square foot and is determined by the painter’s time and the price of paint.

Therefore, K is the only factor that will change if the customer asks for a more expensive brand of paint.
