17 190

A ratio of 1:7 indicates in the problem that three half lives have expired. Since we know the C14 isotope in the fossil has a half life of 5730 years, we can say that the approximate age of the fossil is 5730*3 yrs= 17,190 years.

Apparently, geography's teachers don't mind about 1 thousand years off.

Physicians would say 16,090 years :
