One day, Ms. Roberts and Mr. Bau take their dog out for a walk. Their
dog decided to be adventurous and befriend a skunk. Unfortunately,
the skunk did not want to play and it sprayed the dog directly and was
also able to wrap both teachers in the stench. The main chemical
component of a skunk’s odor is Butanethiol. The proposed half-life of
this chemical is 87 days. If it sprayed them with a full 15 cubic
centimeters of chemical, how much will still be on them after 60 days?
this question appeared on a test given monday. care to make some guesses? henry?
