42. Bacteria in Sausage The number of Enterococcus faecium bacteria contaminating bologna sausage at 32°C can be de- scribed by the equation N = N, exp{9.8901 exp[-exp(2.5420 – 0.2167t)]},
where t is the time in hours and N, is the number at time t = 0. Source: Applied and Environmental Microbiology. (We have used the notation exp x to represent el because otherwise all the powers raised to powers would make the expression dif- ficult to read.) Suppose No = 100. . a. Find the number of bacteria after 10, 20, 30, 40, and 50 hours. =
