Suppose the cost function associated with a product is C(x) = cx + F dollars and the revenue function is R(x) = sx,
where c denotes the unit cost of production, s the unit selling price, F the fixed cost incurred by the firm, and x the level of production and sales. Find the break-even quantity and the break-even revenue in terms of the constants c, s, and F.

i dont know how to solve it...

"Break Even" is a really big clue.

Try Cost = Revenue and see what happens.

 

[icqvan]

break even quantity
F/(s-c)

Revenue
s(f/(s-c))

it is what i think, but i dont think my answer is correct...
