I NEED HELP ASAP! : An initial population of 175 quail increases at an annual rate of 22%. Write an exponential function to mode
goblinko [34]

Answer:

About 473 quails.

P=175(1.22)^t

Step-by-step explanation:

Exponential equation with P_0 as the initial amount and rate of r is:

P=P_0(1+r)^t

P=175(1+.22)^t

P=175(1.22)^t

After 5 years the population will be:

P=175(1.22)^5

P \approx 472.9739

So the population will be about 473 quails.
