The students in the mathematics and chess clubs worked together to raise funds for their respective groups. Together the clubs raised \(\$ 480\). There are 12 members in the Mathematics Club and only 8 in the Chess Club. How should the funds be divided between the two clubs? Explain your answer. (a)

Short Answer

Expert verified
Mathematics Club receives $288, Chess Club receives $192.

Step by step solution

01

Determine Total Contribution Ratio

First, recognize that the funds should be divided based on the number of members in each club. The Mathematics Club has 12 members, and the Chess Club has 8 members. Therefore, the total number of members is 12 + 8 = 20.
02

Calculate Share for Each Member

The total amount raised is \(480, which should be distributed across 20 members. Therefore, each member's share is calculated as \( \frac{480}{20} = 24 \). This means each member is attributed a value of \\)24 in the total fundraising.
03

Calculate Total Funds for Mathematics Club

The Mathematics Club has 12 members, so we multiply the number of members by the share per member: \( 12 \times 24 = 288 \). This is the amount allocated to the Mathematics Club.
04

Calculate Total Funds for Chess Club

Similarly, for the Chess Club, with 8 members, we multiply the number of members by the share per member: \( 8 \times 24 = 192 \). This is the amount allocated to the Chess Club.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Problem Solving
When faced with a problem, it's crucial to break it down into manageable steps. This approach helps in examining all aspects of the problem thoroughly, leading to effective solutions. Let's take the example of dividing funds raised between two clubs.
To begin, assess what you know:
  • Identify the total funds raised: $480.
  • Determine the number of members in each club—12 in the Mathematics Club and 8 in the Chess Club.
Next, devise a plan by setting up a ratio based on club memberships. This helps equitably split the total funds raised.
  • Calculate a fair share per club member based on each club's total membership proportion.
By systematically addressing each part of the problem, you reach a solution that is fair and understandable.
Careful planning and execution are key in any problem-solving scenario. It involves recognizing known data, developing an approach, executing computations, and analyzing solutions for reasonableness.
Ratios and Proportions
Ratios and proportions are mathematical tools used to express a relationship between numbers. They provide a method to divide quantities based on a predefined relation. In our clubs' scenario, the concept of ratios is particularly useful for fair distribution.
Imagine you need to divide a pizza between friends. If one friend eats more than the other, a ratio could outline the fraction each should receive based on their appetite.In this exercise:
  • The ratio of mathematics club members to total members is \((12:20) \).
  • The ratio for the chess club is \((8:20)\).
This means the Mathematics Club gets \((\frac{12}{20})\) of the total funds, whereas the Chess Club receives \((\frac{8}{20})\).Through these calculations:
  • The Mathematics Club receives \(288\) dollars.
  • The Chess Club receives \(192\) dollars.
Ratios and proportions ensure that everyone receives a fair share relative to their membership count.
Mathematical Reasoning
Mathematical reasoning is all about using logical thinking to solve problems. It's like a detective solving a mystery, piecing clues together to find the answer. In our fundraising exercise, the reasoning ensures each step logically follows the previous.Begin by establishing a foundation:
  • Understand why dividing funds by membership is fair—each member contributed equally.
  • Verify by multiplying total members by the share per member to cross-validate the total funds.
Reasoning helps confirm that each step in the calculation aligns with the problem's objective of equitable distribution. Here's how:
  • Mathematics Club: \(12 \times 24 = 288\), Chess Club: \(8 \times 24 = 192\).
  • Together, \(288 + 192\) equals \(480\), matching the total funds.
Each piece of the puzzle adds up through logical and numerical congruence, ensuring a comprehensive problem-solving approach. Always reason through each step to ensure accuracy and fairness.
