A radioactive Isotope decays at a rate proportional to the amount present. If the Isotope has
a decay rate of 12.10% per thounsands of years and the current amount of the isotope is
135.2 mg. How much of the isotope will remain after 2.2 thounsand years? Round your
answer to the nearest tenth.

a- 101.8
b- 99.8
c- 90.3
d- 129.7

Round 0.866 to the nearest hundredth
