A population of deer has a per capita rate of increase of 0.1 deer per year. If there are initially 300 deer in the population,
Burka [1]

Answer:

c) 330

Explanation:

Formula to calculate exponential growth is written as:  

                 y = a( 1+r)ⁿ

a = initial quantity  

r = growth rate as a decimal

n = number of time intervals  

y = quantity after n time

As per the question given  

a = 300

r = 0.1  

n = 1 year

y = ?

Thus,

y = a( 1+r)ⁿ    

300(1+0.1)¹

300 × 1.1 = 330

Therefore,

y = 330
