Apopulation of bacteria decreases at the rate of 13.2% in one hour. what is the hourly growth factor?

Hello, Hello, to find the growth rate, visualize the following formula
A = P(1-r)^t

The r in (1-r) is the decrease  rate = 13.2% = .132. The (1 - r)  is the growth factor. So 1 - .132 = .868 growth factor. With that said, it would help to know what model is being use for the population and growth / decrease.
