Explanation:
 
Given, for a 4 inch wide crown molding: 
 
8 ft length costs $14 
 
Cost of 40 ft length = ? 
 
 
 
8 ft length costs $14 
 
To find the cost of 1 ft length, 
 
Divide through by 8 
 
8ft/8 length costs $14/8 
 
1ft costs $1.75 
 
 
 
Now, to find the cost of 40 ft length 
 
1ft costs $1.75 
 
1 ft x 40 would cost $1.75 
 
40 ft would cost $70 
 
 
 
Therefore, it would cost $70 to buy 40 ft of crown molding
