Because they divide initial concentration by final concentration, you get a value of 10 in the ln and would therefore set ln(10) = k*t. If you divided final concentration by initial concentration instead, you would get a value of 0.1 in the ln, but you would have to set ln(0.1) = - k*t according to the equation ln[A] = -k*t + ln[A]0. They just flipped it around so that positive k*t = ln([A]0/[A]).
