carlosegoFor this case we have a function of the form: y = A * (b) ^ t Where, A: initial amount b: decrease rate t: time We must find the values of A and b. For this, we evaluate the following points: (0, 30): 30 = A * (b) ^ 0 30 = A * 1 30 = A (1, 28.5): 28.5 = 30 * (b) ^ 1 28.5 = 30 * b b = 28.5 / 30 b = 0.95 Answer: the decay factor of the data is: b = 0.95
