Geometric Prompting

The unit test is on Wednesday and the deadline is getting close to get your blogging done. In an effort to make your lives easier ;-) by giving you things to blog about consider this problem:

A student strained her knee in an intramural volleyball game, and her doctor prescribed an anti-inflammatory drug to reduce the swelling. She is to take two 220-milligram tablets every 8 hours for 10 days. Her kidneys eliminate 60% of this drug from her body every 8 hours.

Blogging Prompt
  1. How much of the drug will remain in her body after 10 days, just after she takes her last dose of medicine? If she continued to take the drug for a year, how much of it would be in her system just after she took her last dose?
  2. If the initial dose is halved, what will happen to the stabilization level of the medicine in the body?
  3. If the recurring dose is halved, what will happen to the stabilization level of the medicine?
  4. If the elimination rate is halved, what will happen to the stabilization level of the medicine?

A successful response to this blogging prompt will answer #1 above and at least one of #2 - #4. It will also show all work done to get the answers. If you want to check your work you can use this interactive applet. Instructions on how to use the interactive applet are here.

Have Fun and Happy Blogging!!
