Students headed into finals week need to blow off some steam, so let’s have a little fun with calculus. Hey, Niner, does this look familiar?…

can you please solve this? “in a certain math course, a student needs between 720 and 810 points in order to get a B. the final exam worth 200 points. if Cathy has 584 points just before the finals, what range of scores on the final exam will give her a B for the course?

Hi, lyra jane, and thank you for stopping by!

You can solve your problem with a little bit of logic. Start thinking this way:

*If Cathy got 1 point on the final, would that be enough to give her a B?*What if she got 10 points?*100 points?*What is the least number of points that would give her a total of 720? That is the beginning of the range of scores you are looking for.This is hilarious. I can’t wait to show my son. Thanks!
