Each year,tree makes 1 lb. more fruit than year before:If morethan 700 lbs. of fruit,how old is tree

Question

I can't figure out how to make this an algebra problem.  It seems like an add 1 per year addition problem, which would make the tree at least 700 years old, but I know that's not right.

Answer 1

it is 37 when u round it up but when u dont round it up it is 703

Answer 2

Thank you for replying, but I still don't understand.  How does 703 round up to 37?  Can you show me some of the work?
