    ok the initial difference in temperature is \[70-33=37\] after 3 minutes it is \[70-38=32\] degrees so you can use \[37\times (\frac{32}{37})^{\frac{t}{3}}\] for the temperature difference after t minutes

    try \[37(\frac{32}{37})^{6}\] and see what you get.

    i get about 15.54 as the differnce between the room and the beer, making the beer 70 - 15.54 = 54.46 rounded
