=Pt280+16e−0.45t

Round your answers to the nearest whole number as necessary.

As I understand the formula is

P(t) = 280+16*e^(-0.45*t).

The initial population size is P(0)=280+16*1=296.

After 10 years is P(10)=280+16*e^(-4.5)=280.177... approx =280.

The formula I guessed seems strange... please respond. Maybe "*" instead of "+"?

I copied it as it was in the text. It is suppose to be addition though
