Final answer:
To find p(t) at 10 and 25, substitute the given values of t into the equation: p(10) ≈ 72 and p(25) ≈ 135.
Step-by-step explanation:
To find p(t) at 10 and 25, we need to substitute the values of t into the given equation. Let's start with t=10.
p(10) = 600 / (1 + 30e^(-0.2*10))
p(10) = 600 / (1 + 30e^(-2))
p(10) = 600 / (1 + 30e^(-2))
p(10) = 600 / (1 + 30e^(-2))
p(10) ≈ 72
Now let's find p(25).
p(25) = 600 / (1 + 30e^(-0.2*25))
p(25) ≈ 135
