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.

And given the Revenue function:

We must equate them:

Since "x" represents the number of computers that AB Computer Company must sell to break even, we have to solve for "x" in order to find its value.

Then:

Therefore, the AB Computer Company must sell 10 computers to break even.
