You can  put this solution on YOUR website! Hey,
 
For this one, we need to put the cost, C(x), which is 978, into the equation:
 
978 = .7x + 682
 
We subract 682 from both sides:
 
296 = .7x
 
We then divide both sides by .7:
 
x = 422.857...
 
Therefore:
 
423 units can be produced.
 
I hope this helps!
