Calculating the Number of Jelly Beans Kelly Receives

Oct 13, 2025 by wbrum.org 25 views

Introduction

In this problem, we are presented with a scenario where Kathy distributes jelly beans among her friends. We are given information about the number of jelly beans Alia and Kelly receive, and we need to determine the number of jelly beans Alia gets. To solve this problem, we need to understand the mathematical concepts involved, specifically exponentiation and subtraction.

Calculating the Number of Jelly Beans Kelly Receives

First, let's calculate the number of jelly beans Kelly receives. We are given that Kelly gets $$3^3$$ jelly beans. To calculate this, we need to raise 3 to the power of 3.

3^3 = 3 \times 3 \times 3 = 27

So, Kelly receives 27 jelly beans.

Calculating the Number of Jelly Beans Alia Receives

Next, let's calculate the number of jelly beans Alia receives. We are given that Alia gets $$4^2$$ fewer jelly beans than Kelly. To calculate this, we need to raise 4 to the power of 2 and then subtract the result from the number of jelly beans Kelly receives.

4^2 = 4 \times 4 = 16

Since Alia gets $$4^2$$ fewer jelly beans than Kelly, we need to subtract 16 from the number of jelly beans Kelly receives.

27 - 16 = 11

So, Alia receives 11 jelly beans.

Conclusion

In conclusion, to solve this problem, we need to understand the mathematical concepts involved, specifically exponentiation and subtraction. We calculated the number of jelly beans Kelly receives by raising 3 to the power of 3, and then we calculated the number of jelly beans Alia receives by raising 4 to the power of 2 and subtracting the result from the number of jelly beans Kelly receives. The correct answer is 11.

Answer

The correct answer is B. 11.
