Select the correct answer. Charlie is installing new carpet in his rectangular living room, which is 5 feet longer than it is wide. He has received quotes for the total installation costs from two different contractors for the same style of carpet. Contractor A charges an installation fee of $125 plus $2 per square foot for the carpet. Contractor B charges an installation fee of $75 plus $2.50 per square foot for the carpet. Based on this information, which system of equations could be used to determine the width of the living room, x, in feet, at which the quote for the installation costs, y, is the same for both companies?
