An ice cube of mass 40g is transferred directly from the freezer where it is at -8 CELSIUS to a cup containing 120g of water at 95 degrees CELSIUS. Calculate the final temperature of water. Ignore any heat transfer to the cup or its surroundings

2. Relevant equations

tf = ti + delta t

Is there a possibility elimination/substitution is involved? :S

3. The attempt at a solution

0.04 (2.1 x 10^3)(delta t) + (0.12)(4.18 x 10^3)(delta t)

I solved for it and its wrong. The teacher gave us the answer, but not how to solve it so we can check it later. The answer is 50 degrees Celsius. Can someone show me how they solved it? :S
