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
18 3/4 is equal to 18.75, so 18.75x2.80 is your original cost (52.5). After doing that, since 52.5=100% you are going to divide 52.5 by 5 since 20x5=100. So 20% is 10.5. 52.5-10.5= $42.00
