4Since the population is increasing, apply exponential growth: y= a (1+r)^t
The population starts at 1, therefore, a=1, and the population quadruples, "quad" means four, therefore, y=4. T=1, r= the rate of the population, you are trying to solve for r.
Steps:
1. 4= 4(1+r)^1
2. Apply PEMDAS
3. 4=1(1+r)
4. 4= 1+r
5. Subtract the 1 on both sides.
6. r=3
7. R = 3 or 300%.
Your answer is 300%.
