Snowshine Floors Carpeting is hired to lay down carpet in R rooms of equal size. Snowshine Floor’s fee can be calculated by the Expression RCLW, where R is the number of rooms, C is the cost per square foot of the carpet in dollars, L is the length of each room in feet, and W is the width of each room in feet. If the customer chooses to use more expensive material for the carpet, which of the factors in the expression would change?
Choice B is correct.
Since, the customer chooses to use more expensive material for the carpet. The impact on the various parameters (variables) will be as follows:
R: The number of rooms remains the same (R remains constant)
C: The cost per square foot in dollars will increase (C will increase)
L: The length of rooms is not altered (L remains constant)
W: The width of rooms is not altered (W remains constant)
Therefore, amongst the various parameters, only C will increase.
