At 7:00am, Alicia pours a cup of tea whose temperature is 200 degrees. The tea starts to cool to a room temperature of 72 degrees. An exponential model for the temperature of the tea is y = 128(0.988)^x+ 72, where y is the temperaturex minutes after 7:00 amwill tea when its temperature x is minutws after 7:00am. Alicia will drink the tea when its temperature is 170 degrees. When can Alicia drink the tea?
