If a population of 200 squirrels has a 10 percent growth rate each year, how many individuals will there be in the population after 3 years (assume that no deaths occur during this period)

For this case we have a function of the form:
 y = A * (b) ^ t
 Where,
 A: initial amount
 b: growth rate
 t: time
 Substituting values we have:
 y = 200 * (1.10) ^ (t)
 For 3 years we have:
 y = 200 * (1.10) ^ (3)
 y = 266.2
 Rounding off we have:
 y = 266
 
 there will be 266 squirrels in the population after 3 years

I'm gonna have to say about 13 percent
