To find the total cost for the decorating job, we can follow the five-step thinking plan:
Step 1: Identify the problem
The problem is to determine the total cost for the decorating job, considering the cost per roll of wallpaper for the walls and the border, as well as the number of rolls required for each.
Step 2: Gather information
Given information:
- Cost per roll for walls: $18
- Cost per roll for border: $11
- Number of rolls required for walls: 14
- Number of rolls required for border: 8
Step 3: Formulate a plan
To find the total cost, we will multiply the cost per roll by the number of rolls for each part (walls and border), and then add them together.
Step 4: Solve the problem
The cost for the walls can be calculated as:
Cost for walls = Cost per roll for walls × Number of rolls for walls
Cost for walls = $18 × 14 = $252
The cost for the border can be calculated as:
Cost for border = Cost per roll for border × Number of rolls for border
Cost for border = $11 × 8 = $88
The total cost for the decorating job is the sum of the costs for the walls and the border:
Total cost = Cost for walls + Cost for border
Total cost = $252 + $88 = $340
Step 5: Evaluate the solution
The total cost for the decorating job is $340.
Therefore, the blank space should be filled with $340.
To find the total cost for the decorating job, you need to calculate the cost of wallpaper rolls for the walls and the cost for the border separately, and then add them together.
Step 1: Identify the given information:
- Cost per roll for the walls: $18
- Cost per roll for the border: $11
- Number of rolls for the walls: 14
- Number of rolls for the border: 8
Step 2: Calculate the cost for the walls:
To find the cost for the walls, multiply the cost per roll ($18) by the number of rolls for the walls (14):
Cost for the walls = $18 * 14
Step 3: Calculate the cost for the border:
To find the cost for the border, multiply the cost per roll ($11) by the number of rolls for the border (8):
Cost for the border = $11 * 8
Step 4: Add the costs of walls and border:
Total cost for the decorating job = Cost for the walls + Cost for the border
Step 5: Substitute the calculated values into the equation:
Total cost for the decorating job = ($18 * 14) + ($11 * 8)
Now, you can perform the calculations:
Total cost for the decorating job = $252 + $88
Finally, add the two amounts together:
Total cost for the decorating job = $340
So, the total cost for the decorating job is $340.
