Answer to We are making a cup of coffee and want the temperature to be just right, so we measure the temperature with both Fahrenheit and CelsiusTo find when the coffee is $140$ degrees we want to solve $$ f(t) = 110e^{008t} 75 = 140 $$ Subtracting $75$ from both sides and then dividing both sides by $110$ gives $$ e^{008t} = \frac{65}{110} $$ By the definition of the natural logarithm, this gives $$ 008t = \ln{\left(\frac{65}{110}\right)} $$ Dividing both sides by $008
