it was 6 when it was planted so it is going to have +6 with no variable
OpenStudy (graciebugg):
I did 46.5/6 before reading the answers so now I dunno what to do.
Mehek (mehek14):
no you don't divide by 6
OpenStudy (graciebugg):
ok....What do I do?
Mehek (mehek14):
you need to know how much it grew per month for 15 months
