In the middle of the twentieth century, prehistoric cave paintings of animals were found in a cave. Scientific analysis revealed that only 16% of the original carbon-14 in the paintings remained. What is an estimate of the age of the paintings? (The half-life of carbon-14 is 5730 years.) The paintings are approximately ...years old. (Do not round until the final answer. Then round to the nearest year as needed.)
