The number of pancakes y is proportional to the cups of pancake mix × that is used to
make the pancake batter. The pancake
batter will make 10 pancakes when 2 cups
of pancake mix is used. Write an equation
that represents the situation.

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?
