CARPETING
Facts about Carpets:
(1) Carpets are usually 3⁄4 yard wide and are sold by the linear yard.
(2) Always draw a diagram of the floor or stairs to be covered.
(3) The number of yards required depends on which way the strips run—whether lengthwise or across the room. Sometimes by running the strips lengthwise, there is less waste in matching the pattern.
(4) The part cut off in matching patterns is charged to the purchaser.
Rules for Estimating:
The number of yards required will be the number of yards in a strip (including the waste for matching), multiplied by the number of strips.
Example: What is the cost of carpeting a room 16 feet by 24 feet at 85c per yard? The carpet is 21⁄4 feet wide and the strips run lengthwise.
