Writeacher is correct. I never would have clicked on uah.
How much heat was gained by the cold water?
mass x specific heat x (Tfinal-Tinitial) = ??
How much was lost by the hot water?
mass x specific heat x (Tfinal-Tinitial) = ??
What's the difference? The difference is how much was absorbed by the calorimeter. Take the difference and divide by delta T to find cCal. You don't say what the initial T of the calorimeter was; perhaps it was 20, the same as the cold water. Perhaps it was something different but delta T will be Tfinal (45 C?) - Tinitial.
