Answer:
The Company AB must sell 116 computers to break even 
Step-by-step explanation:
we have
 -----> equation A
 -----> equation A
 ----> equation B
 ----> equation B
where
C is the cost function
R is the revenue function
x is the number of computers sold
we know that
Break even is when the cost is equal to the revenue
so
equate equation A and equation B

Solve for x
subtract 1/4x both sides



Divide by 1.25 both sides

therefore
The Company AB must sell 116 computers to break even
