17. Carbon-14 is present in all living organisms and decays at a predictable rate. To estimate the age of an organism, archaeologists measure the amount of carbon-14 left in its remains. The approximate amount of carbon-14 remaining after 5000 years can be found using the formula = A଴(2.7)ି య ఱ , where A଴ is the initial amount of carbon-14 in the sample that is tested. How much carbon-14 is left in the sample that is 5000 years old and originally contained 7.0 × 10ିଵଶ grams of carbon-14?
