Estimate final temperature of the combined metals

Question: A 10.0g sheet of gold with a temperature of 18C is laid flat on a sheet of iron that weighs 20.0g and has a temperature of 55.6C. Given that the specific heats of AU and Fe are 0.129 J/gC and 0.444 J/gC, respectively, what is the final temperature of the combined metals? assume that no heat is lost to the surroundings.(hint: heat gained by gold must be equal to the heat lost my the iron.)
