Final answer:
To find the cost for 56 ft of crown molding, first determine the cost per foot by dividing 12 dollars by 8 ft, getting 1.5 dollars per foot. Then, multiply by 56 ft to get the total cost of 84 dollars.
Step-by-step explanation:
The cost of crown molding is given for an 8 ft length which is 12 dollars. To find the cost of 56 ft, we first determine the cost per foot and then multiply this by 56 ft.
First, we calculate the cost per foot:
- Cost per foot = total cost / length in feet
- Cost per foot = 12 dollars / 8 ft
- Cost per foot = 1.5 dollars per foot
Next, we calculate the cost for 56 ft:
- Total cost for 56 ft = cost per foot * length needed
- Total cost for 56 ft = 1.5 dollars per foot * 56 ft
- Total cost for 56 ft = 84 dollars
Therefore, it will cost 84 dollars to buy 56 ft of crown molding.
