The equation representing the elapsed time, m, in minutes, since the coffee was left to cool, and the temperature of the coffee, T, measured in °C is:

$T(m)=21+74.10^{-0.03 m}$

Compute the temperature of the coffee after 10 minutes as follows:

$T(10)=21+74.10^{-0.03 \times 10}$

$=21+0.274824\\=21.274824\\\approx 21.27^{o}\ C$

Thus, the temperature of the coffee after 10 minutes will be 21.27°C.
