Options include creating a table, graph, or equation.
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
Subtract $20 from both sides:
$57.50 - $20 = 7.50h
37.50 = 7.50h
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.
