Using Spreadsheets to Solve Application Problems
I teach algebra and am curious if GeoGebra can step a student through the solution of an application problem like this: GG invests Fr500 more at 5% than at 3.5% and earns Fr187 in interest. How much did she invest at each rate?
On the attached file you can see a table that is made into an equation in both the CAS and Algebra views. Then I'm stymied how to use the answer to check, again showing it in the spreadsheet. Better still is there a way to make the student preform for each step? In this example, distribute, combine like terms, subtract from both sides and then substitute to check? I couldn't find any pre-made materials like this, but that would be GREAT. Thanks!
