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 233 mg of bismuth-210, how much remains after 8 days?

Me with this one question, and i'll upvote the brainliest answer

If 3x+8=3x+8 is it one solution or no solution
