The elevation E, in meters, above sea level at which the boiling point of a certain liquid is t degrees Celsius is given by the
otez555 [7]
Given function is 

E(t) = 1100(80 - t) + 500(80 - t)^2

At t= 79.5 degree.

So we can place t= 79.5 in given equation

E(79.5) = 1100 (80 - 79.5) + 500* (80 - 79.5)^2

                    = 1100 * 0.5 + 500 * (0.5)^2
                     = 550 + 500 * 0.25
                    = 550 + 125 = 625

So elevation equal to 625 meter at t = 79.5 degree.
