Lets list what we know:
1.5 cups = 18 cookies
How many cups in 1 cookie will help us find the answer:
1.5 / 18 (1.5 cups per 18 cookies)
divide both sides by 1.5 (to get how many cookies in 1 cup)
1 / 12 (1 cup = 12 cookies)
Now, how many times does 12 fit in 30?
30/12 = 2.5
This means it takes 2 and a half cups of raisins to get 30 cookies.
If anything is still unclear please comment,

Answer:
the constant rate of change is 20
Answer: D) No; If x is 5, the expression on the left simplifies to 8, making the inequality false.
In other words, if x = 5, then x+3 becomes 5+3 which ultimately becomes 8, but this is not greater than 8 on the right side.
Your steps could look like this
x+3 > 8
5+3 > 8 ... replace x with 5
8 > 8 ... this is a false inequality
