326/1000 is a different from of .326.
So the answer that Yunuzaj put is correct
to account for the room tempurature you would have to find some complicated equation to solve this but you could assume that the tempurature rate would slow down as it gets closser to room tempurature
if you didn't have to account for the room tempurature
the ending tempurature would be -50 degrees F
because 325-200=125
so 125=10
10 times 3=30
so
125 times 3=375
325-375=-50F
I am not going to give you the answer, but I am going to tell you how to do it. You first put 18 over 1, and multiply that by one half. (You multiply across.)
32 would have an exponent of 3 and 55 would have an exponent of 2.
