Question 947630: Newton's law of cooling relates the rate at which a body cools to the difference in temperature between the body and the environment into which it is introduced. The formula is F(t) = To + Cb^t, where F(t) is the temperature of the body at time t, To is the constant temperature of the environment into which the body is introduced, and C and b are constants. Use Newton's law of cooling to solve the problem below.
A cup of coffee has cooled from 96� to 50� after 10 minutes in a room at 22�. How long will it take to cool to 40�?

Please note: o is suppose to be a subscript

Form two equations based on the formula.

Some simplification more

and

C now known, and b is easily found.
