Finding the exact price on a strip of fabric that came from one yard?

I have bolts of fabric that are 58" long. I have the price of fabric per yard. I need to break it down to find out exactly how much it cost for one particular strip of fabric that came from that yard (example: 3" strip that is 26" long. The width and length of the fabric strips vary - so I need a formula that will work.

Thanks!

Update: That formula does not work. Say I have a yard of fabric that costs $8. By doing the math ... (26/36)*8, my little 3"x26" would cost me $5.78. That is wrong. The formula is missing a varible - it is missing the width of the fabric (3 inches). How do I add that in?

    58" x 36" = 2088 sq inches.

    Therefore the fabric costs $price/2088 per square inch. -- let's say $10 per yard, so:

    $10.00/2088 sq inches = $00.0048/sq inch

    Square inches of fabric strip = length x width in inches -- for your example, 3"x26" = 78 square inches

    Multiply cost per square inch by number of square inches in strip:

    $0.0048x78=$0.3744

    You can use the algorithm above easily with any price and sizes; figure the number of square inches in the yard goods, compute price per square inch, multiply price per square inch by the square inches in a strip.

    Use fractions. For instance if you know the cost of a yard (36 inches) then you can find the cost of 26 inches by multplying 26/36 * price

    same goes for differing widths. just multiply by the appropriate fraction.
