Questions & Step-by-Step Solutions

If a person saves 15% of his monthly salary and his savings amount to $300, what is his monthly salary? (2000)
  • Step 1: Understand that the person saves 15% of his monthly salary.
  • Step 2: Let the monthly salary be represented by the variable x.
  • Step 3: Write the equation for savings: 0.15 times x equals $300.
  • Step 4: This gives us the equation: 0.15x = 300.
  • Step 5: To find x, divide both sides of the equation by 0.15: x = 300 / 0.15.
  • Step 6: Calculate the right side: 300 divided by 0.15 equals 2000.
  • Step 7: Therefore, the monthly salary is $2000.
  • Percentage Calculation – Understanding how to calculate a percentage of a total amount and how to set up equations based on that.
  • Algebraic Manipulation – Using algebra to isolate variables and solve for unknowns in equations.
