Carbon dating and logarithms

The question is a paleontologist discovers remains of animals that appear to have died at the onset of the Holocene ice age, between 1000 years ago.what range of C^14 to C^12 ratio would the scientist expect to find in the animal remains?

Carbon-14 is created from nitrogen-14 in the upper atmosphere of the earth.

Animals and people that eat these plants take the carbon-14 into their bodies as well.

Carbon-14 in the bodies of animals and plants is constantly decaying.

When scientists first began to compare carbon dating data to data from tree rings, they found carbon dating provided "too-young" estimates of artifact age.

Scientists now realize that production of carbon-14 has not been constant over the last 10,000 years, but has changed as the radiation from the sun has changed.
