A cold beer initially at 33°F warms up to 38°F in 3 min while sitting in a room of temperature 70°F. How warm will the beer be if left out for 18 min?

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.
