y=89.976e^-0.023t where t = Time Elapsed (minutes) and y= Temperature Difference (in degrees)
(a) Use the exponential function to estimate the temperature difference y when 35 minutes have elapsed.
(b) How long will it take for the coffee to reach a temperature of 120 degrees? Hint: We first must find the value of y, which is C-69. Therefore, y=120-69=51. We now use this value of y=51 in the equation and then solve for t=time. You are solving: 51=89.976e^-0.023t
