A Room Initially $20.0^{\circ} \mathrm{C}$ Above the Outside Temperature Cools Exponentially at a Rate Of Exponentially

Short Answer

A room initially $20.0^{\circ} \mathrm{C}$ above the outside temperature cools exponentially at a rate of $20 \%$ per hour. Find the temperature of the room (above the outside temperature) after $150 \mathrm{~min}$ .
