We make small elevators which can hold a maximum of ten passengers. One of the direct materials we use is industrial strength carpeting for the floor of the elevator. The direct material use is 8 square yards for each elevator. The standard cost of this caprpeting is 12 per square yard. last month the carpeting was purchased for 11 square a yard and the production department used an average of 8.5 square yards of carpet to complete a total of 90 elevators.
