F. There will be approximately 455,000 members after 4 years.
Solución
Let’s analyze each of the provided options based on the information that the website starts with 300,000 members and the number of members increases by 11% each year.
1. Modeling the Situation
To model the growth of members, we use the exponential growth formula:
Where:
-
is the number of members after years. -
is the initial number of members. -
is the growth rate (expressed as a decimal). -
is the time in years.
Given:
So, the correct model is:
2. Evaluating the Options
Let’s evaluate each option based on the correct model.
Option A
A. This situation can be modeled by the equation.
Evaluation: Correct. This matches the exponential growth model correctly.
Option B
B. This situation can be modeled by the equation.
Evaluation: Incorrect. Using
as the base of the exponent implies a decay model, which is not appropriate here.
Option C
C. This situation can be modeled by the equation.
Evaluation: Incorrect. This incorrectly applies the growth rate and misplaces the initial value in the exponent.
Option D
D. There will be approximately 33,000 members after 4 years.
Evaluation: Incorrect. Starting with 300,000 members and increasing by 11% each year, the number of members after 4 years is much higher.
Option F
F. There will be approximately 455,000 members after 4 years.
Evaluation: Correct.
Calculation:
Summary of Correct Options
- A. Correct
- F. Correct
All other options are either incorrect or incomplete.
Final Answer:
Options A and F are correct.
Options A and F are correct.

Bonus Knowledge
To model the situation accurately, we need to apply the principles of exponential growth. The correct equation for the membership growth is
. This represents that the initial membership (300,000) gets multiplied by
raised to the power of the number of years,
, showing an 11% annual increase.
After four years, using our equation
, we find that there will be approximately 455,000 members. This calculation reflects the power of compounding: growth builds on itself, leading to more members each subsequent year!
