i'm really lost here. please show me how to solve this

A 0.10 kg piece of copper at an initial temperature of 94 degrees C is dropped into 0.20 kg of water contained in a 0.28 kg aluminum calorimeter. The water and calorimeter are initially at 15 degrees C. What is the final temperature of the system when it reacher equilimbirum?
(Cp of Copper = 387J/kg * degC; Cp of Aluminum = 899 J/kg * degC; Cp of Water = 4186J/kg * degC)

thanks for any help

    The sum of the heats gained in a closed system is zero.

    masswater*cw*(Tf-Tiwater)+masscopper*Cc*(Tf-Ticopper)+massAl*Calum*(Tf-Tialum)=0

    Put the numbers in, solve for Tf.
