Answer:
500 lb
Step-by-step explanation:
Let x lb be the weight of seawater needed to get 17.5 lb of salt.
Now,
x lb - 100%
17.5 lb - 3.5%
Write a proportion:

Cross multiply:

We can use y2-y1/x2-x1 to find the slope. Therefore, we have:
-5-(-13)/8-(-4). That gives us -5+13/8+4, or 8/12 = 2/3.
Hope this helps!
It is already simplified because there is nothing you can divide into both 18 and 25 that would result in whole numbers.
Yes, the slope is 5. You are correct
