Yeah I have to use that but I get 18 and I don't know what to do with it.

I know the answer is 6 months but I don't know how to get to it.

anonymous · Answer

18*0.5=9

anonymous · Answer

huh? lol

anonymous · Answer

You already got it. 0.5 IS the answer. haha

anonymous · Answer

No, It's not. Well it is but I have to find the time. I'll just use a different formula.

anonymous · Answer

It IS. 0.5 is HALF haha


And what is HALF of a year? ^.^

anonymous · Answer

Remember that t is time in YEARS.
So if you get t = 0.5
that means t is HALF of a YEAR.

Which is exactly six months ^.^
