HELP!!!
Carbon dating is used to determine the age of fossils. A fossil was found with 75% of the original carbon-14. The half-life of carbon-14 is 5,730 years. The equation that models the situation is 0.75=(0.5)x5,730.
How old is the fossil?
Choose the answer that gives the correct logarithmic equation and answer.

A. x≈2,865
B. x≈13,805
C. x≈11,460
D. x≈2,378
