Question

A sample of 1.37 million bacteria is observed to grow to 1.7 million after 1 hour. That sample is set aside for an unknown time, and then mixed with some number of a second species of bacteria. The two species do not interact. At the time of mixing, the are a total of 7.6 million bacteria; two hours later 10.3 million, and 4 hours later, 14.1 million bacteria. How many individuals of the second species are present in the mixture after 8 hours? Suggestions: if the growth rates of the first species are k_1, k_2 then, after setting u_1 = exp(2K_1) and u = exp(2k_2), show that you end up solving expiations like y_1 = A + B, y_2 = Au_1 + Bu_2, and Y_3 = A(u_1)^2 + B(U_2)^2, where y_1 = 7.6, Y_2 = 10.3, and y_3 = 14.1. Solve those equations algebraically; put the numbers in after you solve them.
