the ratio R of radioactive carbon to nonradioactive carbon left in a sample of an organism that died T years ago can be approximated by the formula R=A(2.7)-T/8033. here A is the ratio of radioactive carbom to nonradioactive carbon in the living organism. what percent of A is left after 2000 years?

Substitue in 2000 for T. Then you have R/A= 2.72^(-1/4) appx. I don't know exactly where you are in math, but you will have to evaluate the expression with the power. R/A is your answer.
