Systems of linear equations are a powerful mathematical tool that can be used to solve a wide variety of real world problems. Whether it is analyzing profit margins for a business, optimizing production schedules, or even determining the best route for a delivery service, systems of linear equations can provide valuable insights and solutions. However, not all real-world problems can be effectively solved using this method. When choosing a problem for my journal entry, I carefully considered the characteristics of the problem to ensure that it could be successfully solved using a system of linear equations.

The problem that I selected for my journal entry involved determining the optimal mix of two different types of candy to maximize revenue for a candy shop. I knew that this problem could be solved using a system of linear equations because it had several key characteristics that made it a good choice for this method.

One reason why the problem could be solved using a system of linear equations is that it involved multiple variables and constraints. In this case, the variables were the quantities of two types of candy that needed to be determined in order to maximize revenue. The constraints included factors such as the total budget available for purchasing the candy and the amount of space available in the shop for storing the candy. By setting up a system of linear equations based on these variables and constraints, I could easily determine the optimal mix of candy to maximize revenue.

Another reason why the problem could be solved using a system of linear equations is that it involved linear relationships between the variables. In this case, the revenue generated from selling each type of candy could be represented as a linear function of the quantity of that candy. By setting up equations based on these linear relationships, I could easily determine the values of the variables that would optimize revenue.

Finally, the problem could be solved using a system of linear equations because it required finding the intersection point of two or more linear equations. In this case, the intersection point represented the optimal mix of candy that would maximize revenue. By solving the system of equations, I could easily identify this intersection point and determine the quantities of each type of candy needed to achieve the maximum revenue.

In conclusion, the problem of determining the optimal mix of two types of candy to maximize revenue for a candy shop was a great choice for using a system of linear equations. The problem had multiple variables and constraints, linear relationships between the variables, and required finding the intersection point of two or more linear equations. By carefully considering these characteristics, I was able to confidently use a system of linear equations to solve the problem and provide valuable insights for the candy shop owner.
