The answer would be C in my opinion
Answer: The number of batches made by Vanessa last weekend = 5
Number of batches made this weekend =20
Step-by-step explanation:
Let x be the number of batches made y Vanessa last weekend.
Given : This weekend Vanessa made 4 times as many batches as last weekend.
i.e. Number of batches made this weekend = 4x
She made a total of 25 batches for the two weekends.
i.e. 

Divide both sides by 5 , we get

i.e. number of batches made y Vanessa last weekend = 5
Number of batches made this weekend =20
Hence, the number of batches made by Vanessa last weekend = 5
Number of batches made this weekend =20
If you are solving for c you need to divide both sides of the inequality by -5 so c< (or equal to) -30/-5 or c<(or equal to)7
It is hard to show work for this problem because it very similar to a basic addition or subtraction problem.
Just so you have the answer and how to solve. -27 is the answer. Think about it like 41-14 then add the negative back. But I would strongly suggest not writing that as work because you teacher might get confused about what you are doing
