Solving Real-World Problems with Math: A Step-by-Step Guide

Mathematics is an essential tool for solving real-world problems. It helps us make sense of the world around us, make informed decisions, and solve complex problems. In this article, we will explore two real-world problems that involve math and provide step-by-step solutions to each problem.

Punit spends 20% of his pocket money on fast food and 15% on movies. If he spends a total of $2161 on the two items, what is his pocket money?

Step 1: Understand the Problem

Punit spends 20% of his pocket money on fast food and 15% on movies. This means that 35% of his pocket money is spent on these two items.

Step 2: Set Up an Equation

Let's assume Punit's pocket money is x. Since he spends 35% of his pocket money on fast food and movies, the amount he spends on these two items is 0.35x.

We are given that Punit spends a total of $2161 on the two items. This can be represented by the equation:

0.35x = 2161

Step 3: Solve for x

To solve for x, we need to isolate x on one side of the equation. We can do this by dividing both sides of the equation by 0.35:

x = 2161 / 0.35

x = 6180

Conclusion

Punit's pocket money is $6180.

Arti spends 24% of her income on house rent and 20% on food. If she is left with $24080, find her income.

Step 1: Understand the Problem

Arti spends 24% of her income on house rent and 20% on food. This means that 44% of her income is spent on these two items.

Step 2: Set Up an Equation

Let's assume Arti's income is x. Since she spends 44% of her income on house rent and food, the amount she spends on these two items is 0.44x.

We are given that Arti is left with $24080 after spending on house rent and food. This can be represented by the equation:

x - 0.44x = 24080

Step 3: Simplify the Equation

We can simplify the equation by combining like terms:

0.56x = 24080

Step 4: Solve for x

To solve for x, we need to isolate x on one side of the equation. We can do this by dividing both sides of the equation by 0.56:

x = 24080 / 0.56

x = 42943

Conclusion

Arti's income is $42943.

Mathematics is an essential tool for solving real-world problems. In this article, we have seen how math can be used to solve two real-world problems involving Punit's pocket money and Arti's income. By applying mathematical concepts and techniques, we can make sense of the world around us and make informed decisions.

  • When solving real-world problems, it's essential to understand the problem and identify the key variables and relationships.
  • Use mathematical concepts and techniques to represent the problem and solve for the unknown variables.
  • Check your work and ensure that your solution makes sense in the context of the problem.

Conclusion

Mathematics is a powerful tool for solving real-world problems. By applying mathematical concepts and techniques, we can make sense of the world around us and make informed decisions. In this article, we have seen how math can be used to solve two real-world problems involving Punit's pocket money and Arti's income. We hope that this article has provided you with a better understanding of the importance of math in solving real-world problems.
