Best ResponseYou've already chosen the best response.0Because, when t = 1, y = 71.25. When t = 0, y = 95. It went from 95 to 71.25 by multiplying 0.75 by 95, equaling 71.25

Best ResponseYou've already chosen the best response.1so 25% of 95 is 23.75 saying "we lost 23.75 subscribers" is the same as saying "we lost 25% of our subscribers" (going from 95 to 23.75)
