    A company produces cylindrical milk cans with a fixed volume of 500 cm^3. The cost of the material for the top and bottom of the can is 100 VND/cm^2, while the cost for the side wall (lateral surface) is 60 VND/cm^2. Find the radius r of the base that minimizes the total production cost of the can.

    Review the material in this course and identify three different topics (one from each Assessment 1, 2, and 4) that you are interested in and that relate to a scenario you might encounter (or have encountered) in your personal or professional life. To do this, review the material covered in the resources and assessments to get ideas for applying the material to everyday life problems. Clearly label each example and the assessment it comes from. Here are the Assessment titles:

    • Assessment 1: Order of Operations, Fractions, and Percents.
    • Assessment 2: Measurements, Signed Numbers, and Powers of 10.
    • Assessment 4: Linear Equations, Formulas, Proportions, and Systems of Linear Equations.

    For example, here is a scenario using linear equations (Chapter 7 of the text) from Assessment 4:

    Assessment 4 Linear Equation

    Problem : Suppose you have $15,000 in a savings account to pay for your children’s education and you contribute $225 a month to it. How many months will it take for the balance to reach $30,000?

    Solution: The balance y follows the linear equation y = 15000 + 225x, where x is the number of months. So, you need to solve the equation 30000 = 15000 + 225x. Subtracting 15000 from both sides gives 15000 = 225x. Dividing by 225 gives x = 15000/225 = 66.666 . . . , so you will need 67 months (or 5 years and 7 months) to reach $30,000.

    In a Word document, write 23 paragraphs for each of the three topics. For each topic:

    • Explain briefly the real-world situation to which it applies.
    • State the problem. Which question should be answered?
    • Explain the solution. What are the mathematical steps necessary to solve the problem?

    1. What is Algebra?

    Algebra is a branch of Mathematics that uses letters and symbols to represent numbers and quantities in formulas and equations. These letters are called variables and they help us solve problems where some values are unknown.

    Example:
    If +5=10x+5=10, we can find the value of x by subtracting 5 from both sides.
    So, =5x=5.


    2. Basic Terms in Algebra

    • Variable: A symbol (usually a letter) that represents an unknown value.
      Example: ,,,x,y,a,b
    • Constant: A fixed value that does not change.
      Example: 3,7,103,7,10
    • Coefficient: A number multiplied with a variable.
      Example: In 55x, 5 is the coefficient.
    • Expression: A combination of variables, numbers, and operations.
      Example: 3+73x+7
    • Equation: A mathematical statement that shows two expressions are equal.
      Example: 2+4=122x+4=12

    3. Types of Algebraic Expressions

    1. Monomial one term
      Example: 66x
    2. Binomial two terms
      Example: +3x+3
    3. Trinomial three terms
      Example: 2+2+1x2+2x+1

    4. Basic Operations in Algebra

    Algebra involves the following operations:

    • Addition
    • Subtraction
    • Multiplication
    • Division

    Example:
    3+2=53x+2x=5x


    5. Importance of Algebra

    Algebra is important because it:

    • Helps solve real-life problems.
    • Forms the foundation for advanced topics like Calculus and Linear Algebra.
    • Is widely used in science, engineering, economics, and technology.

    Conclusion:
    Algebra simplifies mathematical problems by using symbols and rules to find unknown values. It is a fundamental part of mathematics and is essential for higher-level problem solving.
