Jenny studied the characteristics of two species of bacteria. The number of bacteria of species A, A (t), after t hours is represented by the function, A (t) = 5 + (0.25t) 3. The number of bacteria of species B, B (t), after t hours is represented by the function, B (t) = 2 + 8 (1.06) t. Which function describes the difference in the number of bacteria, N (t), of both the species after t hours?

The function that describes the difference in the number of bacteria, N (t), of both species after t hours is the subtraction of the function A (t) = 5 + (0.25 t) 3 minus the function B (t) = 2 + 8 (1.06) t.

Then the function N (t) is represented by:

N (t) = A (t) - B (t)

N (t) = 3 + (0.25t) 3 - 8 (1.06) t
