a) Find the number of units produced if the revenue is $800.

I really need help with this, I don't know what to do?

**Reiny**, Friday, February 3, 2012 at 8:31amjust set R(x) = 800

800 = 10x - .02x^2

.02x^2 - 10x + 800 = 0

using the quad formula

x = (10 ± √36)/.04 , ahhh it would have factored

= (10 ± 6)/.04

= 400 or 100 units

**Reiny**, Friday, February 3, 2012 at 10:59amsub in your answer

R(1000) = 10(1000) - .02(1000)^2 = -10 000

my answers

R(400) = 10(400) - .02(400)^2 = 800

R(100) = 10(100) - .02(100)^2 = 800

Why are you confused?

how did you possible get 1000?
