How many computers must the ab computer company sell to break even? let x be the number of computers.

cost function: c(x)=145+1/4x

revenue function: r(x)=15x

enter in the number of computers only.

The Company AB must sell 116 computers to break even

Step-by-step explanation:

we have

-----> equation A

----> 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

x + 4/7
