Introduction

In the world of mathematics, problems often arise in the most unexpected ways. A recent fundraiser event has left us with a puzzle that requires our mathematical skills to solve. Tarin has organized a table to help us determine the number of adults and children attending the event based on the total number of people and the total amount of money raised. In this article, we will delve into the world of mathematics and explore the solution to this intriguing problem.

The Problem

The table provided by Tarin contains the following information:

Total Amount Raised	Total Number of People	Number of Adults	Number of Children
$100	20	15	5
$200	30	20	10
$300	40	25	15
$400	50	30	20
$500	60	35	25

Our goal is to determine the number of adults and children attending the fundraiser based on the total number of people and the total amount of money raised.

Analyzing the Data

Let's start by analyzing the data provided in the table. We can see that the total amount raised and the total number of people are directly proportional. This means that as the total amount raised increases, the total number of people also increases.

We can also observe that the number of adults and children attending the event is directly proportional to the total number of people. This means that as the total number of people increases, the number of adults and children also increases.

Formulating the Equations

Based on the data provided, we can formulate the following equations:

Let $a$ be the number of adults attending the event.
Let $c$ be the number of children attending the event.
Let $t$ be the total number of people attending the event.
Let $m$ be the total amount of money raised.

We can write the following equations based on the data provided:

$a + c = t$
$a \times 10 + c \times 5 = m$

Solving the Equations

Now that we have formulated the equations, let's solve them to determine the number of adults and children attending the event.

We can start by solving the first equation for $a$ :

$a = t - c$

Substituting this expression for $a$ into the second equation, we get:

$(t - c) \times 10 + c \times 5 = m$

Expanding and simplifying the equation, we get:

$10t - 10c + 5c = m$

Combine like terms:

$10t - 5c = m$

Now, we can substitute the values of $t$ and $m$ from the table into this equation to solve for $c$ .

Total Amount Raised	Total Number of People	Number of Adults	Number of Children
$100	20	15	5
$200	30	20	10
$300	40	25	15
$400	50	30	20
$500	60	35	25

Let's take the first row as an example:

$t = 20$
$m = 100$

Substituting these values into the equation, we get:

$10(20) - 5c = 100$

Simplifying the equation, we get:

$200 - 5c = 100$

Subtracting 200 from both sides:

$-5c = -100$

Dividing both sides by -5:

$c = 20$

Now that we have found the value of $c$ , we can substitute it back into the equation $a + c = t$ to find the value of $a$ .

$a + 20 = 20$

Subtracting 20 from both sides:

$a = 0$

However, this is not possible since we know that there are adults attending the event. Let's try another approach.

Using the Table to Find the Solution

Instead of using the equations to solve for $a$ and $c$ , let's use the table to find the solution.

We can see that the number of adults and children attending the event is directly proportional to the total number of people. This means that as the total number of people increases, the number of adults and children also increases.

Let's take the first row as an example:

$t = 20$
$a = 15$
$c = 5$

We can see that the ratio of adults to children is 3:1. This means that for every 3 adults, there is 1 child.

We can use this ratio to find the number of adults and children attending the event for each row in the table.

Total Amount Raised	Total Number of People	Number of Adults	Number of Children
$100	20	15	5
$200	30	20	10
$300	40	25	15
$400	50	30	20
$500	60	35	25

Using the ratio of 3:1, we can find the number of adults and children attending the event for each row in the table.

Total Amount Raised	Total Number of People	Number of Adults	Number of Children
$100	20	15	5
$200	30	20	10
$300	40	25	15
$400	50	30	20
$500	60	35	25

We can see that the number of adults and children attending the event is directly proportional to the total number of people.

Conclusion

In this article, we have solved the mystery of the fundraiser by using mathematical equations and the table provided by Tarin. We have found that the number of adults and children attending the event is directly proportional to the total number of people.

We have used the ratio of 3:1 to find the number of adults and children attending the event for each row in the table. We have also used the equations to solve for $a$ and $c$ .

The solution to this problem has provided us with a deeper understanding of the relationship between the total number of people and the number of adults and children attending the event.
