If A' growth rate of number of bacteria at any time t is proportional to number present at any time t and doubles in 1 week than bacteria after four week is
Answer: C
Growth proportional to the amount present gives exponential growth, and doubling every week means the population multiplies by 2 each week.
\[ A(4) = A_{0} \times 2^{4} = 16\,A_{0} \]
The doublings compound rather than add: four weeks give \( 2 \times 2 \times 2 \times 2 = 16 \) times, not \( 2 \times 4 = 8 \) times.
