What is the total entropy change for a 0.490 kg piece of ice at an initial temperature of 0.00 degC if it is placed in a Styrofoam cup having 2.25 kg of water at an initial temperature of 22.7 deg C. (assume the heat transfers in liquid form happen at the average temperature of each individual liquid)

The answer is NOT 29.34 J/K or 1.45 J/K. I've been stuck on this question for days and can't figure it out
