Problem Solving Process

  • A clear problem-solving process is essential.

Steps of the Process

  1. Read the Question

    • Understand what the question is asking and identify the unknowns.

  2. Look for Clues

    • Determine what operations you need: add, subtract, multiply, etc.

    • Clues lead to forming a strategy.

  3. Choose a Strategy

    • Strategies may vary per problem.

    • Options include creating a table, graph, or equation.

  4. Check Your Answer

    • Ensure the solution makes sense in the context of the original question.

Example Problem: Canoe Rental

  • A canoe rental company charges a $20 base fee plus $7.50 per hour. Marcy spent a total of $57.50 on the rental.

Question

  • For how long did Marcy rent the canoe?

Clues from the Problem

  • Base fee: $20

  • Cost per hour: $7.50

  • Total amount spent: $57.50

Strategy

  • Create an equation.

    • Start with the base fee and add the hourly costs:

    • Equation:

      Total Cost = Base Fee + (Cost per Hour × Number of Hours)

    • Let h = number of hours.

    • Therefore, the equation is:

      $57.50 = 20 + 7.50h

Solving the Equation

  1. Subtract $20 from both sides:

    • $57.50 - $20 = 7.50h

    • 37.50 = 7.50h

  2. Divide both sides by $7.50:

    • h = 37.50 / 7.50

    • h = 5

Checking the Answer

  • Insert h = 5 back into the equation:

    • $20 + (7.50 × 5) = $57.50

    • $20 + $37.50 = $57.50

    • The equation holds true.

Conclusion

  • Marcy rented the canoe for 5 hours.

  • The solution is consistent with the original question.
