Word problem with $p$

Question

In the year 2000, there are $p$ penguins. After $t$ years, the number of penguins is given by $$ 2500 \times 1.02^t$$ Calculate the number of penguins in the year $2000$.

I tried to substitute random values for $t$ to get a general pattern but I couldn't get an answer so please help.

Answer 1

In that case, t=0, as there no years have passed since the year 2000. The answer is therefore 2500.
