Final answer:
The equation that represents the situation where the number of people in the crowd decreases by 15% every hour is P(t) = 200 * (1 - 0.15)^t
Step-by-step explanation:
To represent the situation where the number of people in the crowd decreases by 15% every hour, we can use the formula:
P(t) = P(0) * (1 - r)^t
Where:
So the equation that represents the situation is:
P(t) = 200 * (1 - 0.15)^t
