Answer:
A = 450(1.1)^x
Step-by-step explanation:
Since the animal decreases by 10% each year, we will use the compound interest formula to find the required equation
A = P(1+r)^t
P is the number of animals = 450
r is the rate = 10% = 0.1
t is the time = x
Substitute into the formula;
A = 450(1+0.1)^x
A = 450(1.1)^x
This gives the required expression
