Choose The Correct Equation That Represents The Following Situation.Andon Is Offered Two Jobs. One Has A Starting Salary Of $32,000 Plus A Raise Of $1,000 Every Year. The Other Offers A Starting Salary Of $28,000 Plus A Raise Of
Introduction
Mathematics is an essential tool for solving real-world problems. In this article, we will explore a scenario where Andon is offered two jobs with different starting salaries and annual raises. We will use mathematical equations to represent the situation and choose the correct equation that accurately models the problem.
Understanding the Problem
Andon is faced with two job offers. The first job has a starting salary of $32,000, with a raise of $1,000 every year. The second job offers a starting salary of $28,000, with a raise of $1,500 every year. We need to determine which equation represents the situation accurately.
Equation 1: Linear Equation
A linear equation is a mathematical equation that represents a straight line. In this case, we can use a linear equation to model the situation. Let's assume the number of years Andon works is represented by the variable x. The starting salary of the first job is $32,000, and the raise is $1,000 every year. We can represent this situation using the following linear equation:
y = 32,000 + 1,000x
In this equation, y represents the total salary after x years. The equation states that the total salary is equal to the starting salary ($32,000) plus the raise ($1,000) multiplied by the number of years (x).
Equation 2: Linear Equation with a Different Raise
The second job offers a starting salary of $28,000, with a raise of $1,500 every year. We can represent this situation using a linear equation with a different raise:
y = 28,000 + 1,500x
In this equation, y represents the total salary after x years. The equation states that the total salary is equal to the starting salary ($28,000) plus the raise ($1,500) multiplied by the number of years (x).
Choosing the Correct Equation
Now that we have two equations, we need to determine which one represents the situation accurately. Let's analyze the equations:
- Equation 1: y = 32,000 + 1,000x represents the situation where the starting salary is $32,000, and the raise is $1,000 every year.
- Equation 2: y = 28,000 + 1,500x represents the situation where the starting salary is $28,000, and the raise is $1,500 every year.
Based on the problem statement, we can conclude that Equation 2 represents the situation accurately. The starting salary of the second job is $28,000, and the raise is $1,500 every year.
Conclusion
In this article, we explored a scenario where Andon is offered two jobs with different starting salaries and annual raises. We used mathematical equations to represent the situation and chose the correct equation that accurately models the problem. The correct equation is y = 28,000 + 1,500x, which represents the situation where the starting salary is $28,000, and the raise is $1,500 every year.
