Introduction

In this article, we will explore a real-world scenario involving a local minigolf course and use mathematical modeling to represent the situation. We will create a system of equations to describe the number of customers and the total amount of money collected on a particular day. This will involve using variables to represent the unknown quantities and forming equations based on the given information.

The Scenario

On a single day at the minigolf course, there were 320 customers who paid a total of $2,900. The cost for a child's game is $7, and the cost for an adult's game is $10. We can use this information to create a system of equations that models the scenario.

Variables and Equations

Let's define two variables:

  • C: the number of children who played
  • A: the number of adults who played

We can form two equations based on the given information:

  1. Total number of customers: The total number of customers is the sum of the number of children and the number of adults. This can be represented by the equation:

    C + A = 320

  2. Total amount of money collected: The total amount of money collected is the sum of the money collected from children and the money collected from adults. Since children pay $7 per game and adults pay $10 per game, we can represent this as:

    7C + 10A = 2900

System of Equations

We now have a system of two equations with two variables:

C + A = 320 7C + 10A = 2900

Solving the System of Equations

To solve this system of equations, we can use the method of substitution or elimination. Let's use the elimination method to find the values of C and A.

First, we can multiply the first equation by 7 to make the coefficients of C in both equations the same:

7(C + A) = 7(320) 7C + 7A = 2240

Now we have:

7C + 7A = 2240 7C + 10A = 2900

Subtracting the first equation from the second equation, we get:

3A = 660

Dividing both sides by 3, we get:

A = 220

Now that we have the value of A, we can substitute it into the first equation to find the value of C:

C + 220 = 320

Subtracting 220 from both sides, we get:

C = 100

Conclusion

In this article, we used mathematical modeling to represent a real-world scenario involving a local minigolf course. We created a system of equations to describe the number of customers and the total amount of money collected on a particular day. By solving the system of equations, we found the values of C and A, which represent the number of children and adults who played at the minigolf course.
