Question 8 options:
Use the five-step thinking plan to help you solve this problem.
A house painter finds that he needs 20 minutes to set up his equipment before painting and then 5 minutes for every square foot that he paints. How many hours will he need to allow to paint an 800 square foot area?
Blank Space__________hours
To solve this problem using the five-step thinking plan, follow these steps:
Step 1: Understand the problem
The problem states that the painter needs 20 minutes to set up and 5 minutes per square foot to paint. We need to find out how many hours the painter will need to paint an 800 square foot area.
Step 2: Devise a plan
We can calculate the total time needed by adding the time for set up (20 minutes) to the time for painting (5 minutes per square foot multiplied by 800 square feet). Then, we can convert the total time from minutes to hours.
Step 3: Carry out the plan
First, calculate the time for painting:
5 minutes per square foot x 800 square feet = 4000 minutes
Next, add the time for set up:
4000 minutes + 20 minutes = 4020 minutes
Finally, convert the total time from minutes to hours:
4020 minutes ÷ 60 minutes per hour = 67 hours
Step 4: Look back
We have found that the painter will need 67 hours to paint an 800 square foot area.
Step 5: Communicate the solution
Therefore, the house painter will need to allow for 67 hours to paint the 800 square foot area.

To solve this problem using the five-step thinking plan, follow these steps:
Step 1: Understand the problem. The problem states that the house painter needs 20 minutes to set up his equipment before painting and 5 minutes for every square foot that he paints. We need to determine how many hours he will need to allow to paint an 800 square foot area.
Step 2: Plan a solution. We can calculate the total time needed by adding the time to set up the equipment and the time required to paint the area. Then, we can convert the total time to hours.
Step 3: Solve the problem.
Time to set up equipment: 20 minutes
Time to paint 800 square foot area: 5 minutes/square foot * 800 square feet = 4000 minutes
Total time: 20 minutes + 4000 minutes = 4020 minutes
To convert minutes to hours, divide by 60 (as there are 60 minutes in an hour):
4020 minutes ÷ 60 minutes/hour = 67 hours
Step 4: Check the solution. Based on the calculation, the house painter will need to allow 67 hours to paint an 800 square foot area.
Step 5: Communicate the solution. The house painter will need to allow 67 hours to paint an 800 square foot area.
To solve this problem, we will use the five-step thinking plan:
Step 1: Understand the problem:
We need to determine how many hours the house painter will need to allow to paint an 800 square foot area, given that he needs 20 minutes for setup and 5 minutes for every square foot painted.
Step 2: Devise a plan:
We can calculate the time needed by multiplying the number of square feet by 5 (since he needs 5 minutes per square foot), and then adding the setup time. Finally, we'll convert the total time from minutes to hours.
Step 3: Implement the plan:
Let's calculate the total time needed, step by step.
To calculate the painting time, we multiply the number of square feet by 5 minutes:
800 sq ft * 5 min/sq ft = 4,000 minutes
Next, we add the setup time of 20 minutes:
4,000 minutes + 20 minutes = 4,020 minutes
Step 4: Evaluate the solution:
Now, we need to convert the total time from minutes to hours. Since there are 60 minutes in an hour, we can divide the total minutes by 60:
4,020 minutes / 60 min/hour = 67 hours
Step 5: Answer the question:
Therefore, the house painter will need to allow 67 hours to paint an 800 square foot area.
