Answer:
y = 13,000(1.11)x
Explanation:
According to the problem, the population is expected to grow by 11% yearly. So, the equation that best model this scenario is the last option.
We can get this answer just by observing the coefficient of the variable, it has to indicate more than 1 or 100%, that's why it cannot bet 0.11x, because that shows a decrease.
So, an increase of 11%, would be 100% + 11%, which is 111% or 1.11.
Therefore, the right answer is the last option: y = 13,000(1.11)x
