Answer:

Option (D).

Step-by-step explanation:

Initial population of the deer P_{0} = 4800

Decrease in the population of the deer after every 8 years = \frac{1}{2}\times (\text{Initial population})

Decrease in population is an exponential process, so the expression representing population will be,

P_{t}=P_{0}(1-r)^x

Where P_{t} is the population after 'x' slots of 8 years.

r = fraction of decrease in the population

x = \frac{\text{Number of years}}{8}

By substituting the values of r and x in the expression,

P_{t}=P_{0}(1-\frac{1}{2})^{\frac{t}{8}}

P_{t}=4800(\frac{1}{2})^{\frac{t}{8}}

Therefore, Sylvia should do few corrections in her expression.

(8) should be replaced by (\frac{1}{2}) and \frac{t}{2} should be replaced by \frac{t}{8}.

Option D. will be the answer.
