Data Sufficiency (DS) | Re: Temperature on the Celsius scale (C) is related

To me, you dont need to do any algebra. The fomula will guarantee for one C there is one and only one F and vice versa. Therefore if we know F2-F1 = 45, you know you can get C2-C1.

And statement 2 does not provide enough information.

So the answer is A.
