b.What was the percent growth in Home Depot’s sales from 2002 to 2006? Do all your work by using scientific notation.

How would I complete this?

• Algebra -

So the percentage is x/100 so here it would be x/9.08, x being 5.82.
Thus 5.82/9.08 = 0.641 = 64.1%

To verify that, if you wish, you can do 9.08 x 0.641 = 5.82.

Thank you very much!
