Trace amounts of an element found in organic matter, such as bones, decays at a rate of 10% per millennium under the conditions found at the archeological site. A bone is discovered which has been determined to be 10,000 years old. If the measurement that determined the age of the fossil, found 120 parts per million(ppm) of the element, what parts per million were in the bone 10,000 years ago?
