Explanation -
a. as original ratio is 10/35 , we reduce it to 2:7.
b. as original ratio is 35/45 , we reduce it to 7:9
c. as original ratio is 40:50 , we reduce it to 4:5
 
        
             
        
        
        
12 inches = 1foot
1yard = 3feet
6yards = 18feet
Rerange the question:
If edging cost $2.32 per 1foot stone, and you want a double layer of edging around your flower bed that is 18feet by 3feet. How much will edging you flower bed cost?
Perimter:
2(18+3)=42
And since you want to double it; double the perimeter too.
42(2)=84 
2.32(84)=194.88
        
                    
             
        
        
        
Multiply .6 x 132 and that gets you 79.2 then you add 132 +79.2 =$211.20
