First you have to subtract the two one time costs to find the cost delta:
44,641 - 18,720 = 25,921
Then you would have to subtract the variable costs to find the delta:
24.50 - 12.25 = 12.25 per book
Since we know that the 25921 isn't changing we need to divide by the delta of 12.25 per book to find out how many books it will take to make up the 25921
25,921/12.25 = 2116 Books
Answer:
31
Method:
X + 21 = 52 is the same as 52 - 21 = x. 52 - 21 = 31 so x = 31
