B is just simply the y intercept
Answer:
Each of them had $49 at first.
Step-by-step explanation:
Given:
Cedric and Doug each had an equal amount of money.
Let the number of money they had at first be x
Cedric spent = $35
Doug spent = $28
Cedric Money left = 
Doug Money left = 
the ratio of Cedric money to Doug money was 2:3
Hence the expression can be made as;

Now by cross multiplication method we get;

Now we will use distributive property to elaborate the same;

Combining common terms we get;

Using Subtraction property we get;

Hence $49 they each had at first.
The answer is 20x^18 which is the last option.
The answer is either going to be the second one or the last one I'm going to go to with the last one if it's not the last one is the second one I hope I'm right if I'm not please let me know or if I am let me know
