linen scrolls contain 80.9% of Carbon-14. how old are the scrolls if the half-life for deacy is 5.73X10^3??

plz tell me what type of equation to use.

ln(M/Mo) = -kt

ln = natural log

M = mass left (not needed)

Mo = original mass (not needed)

(M/Mo) = 0.809

k = 0.693/T(half)

T(half) = 5.73X10^3 years.
