I know this is such an easy question, but I completely forgot how to do it. Can someone please help me out? Thanks.

If 57.84 g of nickel (Cp = 0.0946 J/g Degrees C) originally at 97.4 degrees C is placed into a calorimeter with 48.24 g of water (Cp = 4.184 J/g degrees C), it is found that the final equilibrium temp is 37.2 degrees C. What must have been the original temp of the water in the calorimeter?
