Hello, I was wondering if you could help me with a question? Yesterday my daughter came to me and asked if I could help her solve these three problems.
Thanks for helping me out.
First, I would say that using percent in the age of calculators is bit of 'abacus arithmatic'. I know it is still in the curiculum and in lots of vocabulary, but really is just an extra burden on the real issues. [I was struck by this, again, the last time I did my taxes ; ( ]
The WHAT is the variable in an algebra question - so you may have to write something, change the appearance then use the calculator.
