Math Problem Statement
Bismuth-210 is an isotope that radioactively decays by about 13% each day, meaning 13% of the remaining Bismuth-210 transforms into another atom (polonium-210 in this case) each day. If you begin with 269 mg of Bismuth-210, how much remains after 5 days? After 5 days, what mg of Bismouth-210 remains? Round your answer to the nearest hundredth as needed.
