If the cost, C. for manufacturing x units of a certain product is given by C = x2 + 35x + 35, find the number of units manufactured at a cost of $10,235.

Respuesta :

Answer: 85 units

Step-by-step explanation:

x^2 +35x + 35 = 10235

-10235 on both sides

x^2 + 35x -10200

Now Factor

( x - 85 ) ( x + 120 )

Now plug in for x using 85 or -120

(85)^2 + 35(85) + 35

7225 + 2975 + 35 = 10235

So 85 is the right answer
