A.
c = f(b) = 4b – 1
B.
c = f(b) = 4b + 1
C.
c = f(b) = 3b + 4
D.
c = f(b) = 4b + 3
E.

Let me give you some helpful advice before you do so. Remember to help lead the user on to the answer and not give the direct answer giving the direct answer is suspendible although bannable sounds better than suspendable but that's not the point. Help the user do not give the user what they want and don't take that out of context as I said before and time and time again with you help lead the user on to the correct answer.

Answer 4

Since C is the function,and b is the given variable,you would have to start the equation with so (Make sure to write this down so you can double check or paraphrase for constructed response)
C(b)= the number of dollars for the first box,4 dollars
Take out the dollar
C(b) = 4
Next,you add 3(B-1) to the equation C(b)=4
and you will get the next equation which is
You then add the 3(B-1) to the 4 because the additional boxes(B-1) equal 3 dollars and to get the total number of B-1 boxes you multiply|
Put the equation together ans what do you get...
The answer is C!!!
Boom!Mic drop
PS:For constructed response make sure to paraphrase,This is a simplified version fo Order of Operations.Boom

Answer 5

hey if this helps you
c(b)= 4+3(b-1)
