As I don't know enough info I will say how to figure it out,
so you get the amount of cereal in a [eg 40] then you divide it by 10 you get [4] each cup is worth [4] then you divide b [eg 56] by [4] giving you [14] so you get [4]
more cups of cereal in b.
i am presuming thats the info you get in the question and if it is that is how you answer it if not well its your fault for not providing enough info
Answer:
The equation's result: 32,000 (Rounded)
Goal: Find the closest or equivalent result in another expression
Step-by-step explanation:
<h3>A)</h3>

How we got to 31,636 was by dividing from left to right.
Remember: When dividing decimals, it's like multiplying whole numbers in a way. The number(the quotient, also) ends up bigger instead of being smaller like when dividing whole numbers. If you multiply decimals, they(the product) end up smaller.
Therefore, A is the correct answer.
Odd numbers on a dice: 1,3,5= 3 numbers
All numbers on dice: 1,2,3,4,5,6= 6 numbers
P=3/6=1/2=50%
Substitute in f(x) every time you see an x value in g(x)
Hence, g(f(x)) = (4x - 1)^2 + 7
= 16x^2 - 8x + 1 + 7
= 16x^2 - 8x + 8 (ie A)
