Introduction

Sorting laundry is a mundane task that we all have to do from time to time. However, when it comes to math problems, sorting laundry can become a fun and challenging puzzle. In this scenario, we are given that the laundry has been sorted into dark clothes and light clothes, with the number of dark clothes being three more than twice the number of light clothes. Additionally, we are told that the laundry is 60% dark clothes. Our task is to choose the equation that best represents this scenario.

Understanding the Problem

Let's break down the information given in the problem. We have two types of clothes: dark clothes and light clothes. The number of dark clothes is three more than twice the number of light clothes. This can be represented as:

D = 2L + 3

where D is the number of dark clothes and L is the number of light clothes.

The Laundry is 60% Dark Clothes

We are also told that the laundry is 60% dark clothes. This means that the ratio of dark clothes to the total number of clothes is 60%. Mathematically, this can be represented as:

D / (D + L) = 0.6

Choosing the Equation

Now that we have two equations, we need to choose the one that best represents the scenario. The first equation, D = 2L + 3, represents the relationship between the number of dark clothes and light clothes. The second equation, D / (D + L) = 0.6, represents the ratio of dark clothes to the total number of clothes.

Solving the Equation

To solve the equation, we can start by substituting the first equation into the second equation. This gives us:

(2L + 3) / (2L + 3 + L) = 0.6

Simplifying the equation, we get:

(2L + 3) / (3L + 3) = 0.6

Cross-Multiplying

To get rid of the fraction, we can cross-multiply the equation. This gives us:

2L + 3 = 0.6(3L + 3)

Expanding the Equation

Expanding the equation, we get:

2L + 3 = 1.8L + 1.8

Solving for L

Now that we have the equation in a simpler form, we can solve for L. Subtracting 2L from both sides of the equation, we get:

3 = 0.8L + 1.8

Subtracting 1.8 from both sides of the equation, we get:

1.2 = 0.8L

Dividing both sides of the equation by 0.8, we get:

L = 1.5

Finding the Number of Dark Clothes

Now that we have the number of light clothes, we can find the number of dark clothes. Substituting L = 1.5 into the first equation, we get:

D = 2(1.5) + 3

Simplifying the equation, we get:

D = 3 + 3

D = 6

Conclusion

In conclusion, the equation that best represents the scenario is D = 2L + 3, where D is the number of dark clothes and L is the number of light clothes. The ratio of dark clothes to the total number of clothes is 60%, which can be represented as D / (D + L) = 0.6. By solving the equation, we found that the number of light clothes is 1.5 and the number of dark clothes is 6.

Final Answer

The final answer is D = 2L + 3.

Discussion

This problem is a great example of how math can be applied to real-life scenarios. By understanding the relationship between the number of dark clothes and light clothes, we can solve for the number of each type of clothes. This problem also highlights the importance of ratios and proportions in math.

Introduction

In our previous article, we explored the scenario of sorting laundry into dark clothes and light clothes, with the number of dark clothes being three more than twice the number of light clothes, and the laundry being 60% dark clothes. We solved the equation and found that the number of light clothes is 1.5 and the number of dark clothes is 6. In this article, we will answer some frequently asked questions related to this scenario.

Q: What is the ratio of dark clothes to light clothes?

A: The ratio of dark clothes to light clothes is 6:1.5, which can be simplified to 4:1.

Q: What is the total number of clothes?

A: The total number of clothes is the sum of the number of dark clothes and light clothes, which is 6 + 1.5 = 7.5.

Q: What percentage of the laundry is light clothes?

A: Since the laundry is 60% dark clothes, the percentage of light clothes is 100% - 60% = 40%.

Q: If the number of light clothes increases by 10%, what will be the new number of light clothes?

A: If the number of light clothes increases by 10%, the new number of light clothes will be 1.5 + 0.15 = 1.65.

Q: If the number of dark clothes decreases by 20%, what will be the new number of dark clothes?

A: If the number of dark clothes decreases by 20%, the new number of dark clothes will be 6 - 1.2 = 4.8.

Q: What is the average number of clothes per person?

A: Since we don't have information about the number of people, we cannot calculate the average number of clothes per person.

Q: If the laundry is sorted into three piles: dark clothes, light clothes, and mixed clothes, what will be the number of clothes in each pile?

A: Since the laundry is 60% dark clothes, the number of dark clothes will be 60% of the total number of clothes, which is 0.6 x 7.5 = 4.5. The number of light clothes will be 40% of the total number of clothes, which is 0.4 x 7.5 = 3. The number of mixed clothes will be the remaining 10% of the total number of clothes, which is 0.1 x 7.5 = 0.75.

Conclusion

In conclusion, we have answered some frequently asked questions related to the scenario of sorting laundry into dark clothes and light clothes. We hope that this article has provided you with a better understanding of the scenario and has helped you to solve similar problems.

Final Answer

The final answer is D = 2L + 3, where D is the number of dark clothes and L is the number of light clothes.
