Hi there! 5 bottles of water for $3 would make $0.60 per bottle. 0.6 * 15 = 9. That means 15 bottles of water should equal $9, but instead it is $8. Based on that, no. The costs for bottles of water is not proportional to the numbers sold. Basically, you can divide to find unit prices and multiply the number of another item to see if the numbers are proportional.
Answer:
-4 and 1/4

Let the width be w. Therefore we can right the length as w+2=l. We know the formula for perimeter is 2w + 2l = P. We can fill this formula in to help solve this problem with the pieces we have.
2w+2(w+2)=24
2w+2w+4=24
4w=20
w=5
So, we now know the width of the room. Next, lets plug that into the perimeter equation again and solve for the length now.
2(5) + 2l = 24
10 + 2l = 24
2l = 14
l=7
So the width is 5m and the length is 7m.
