A manufacturer of lighting fixtures has daily production costs of

C = 800 − 30x + 0.25x2,

where C is the total cost (in dollars) and x is the number of units produced. How many fixtures should be produced each day to yield a minimum cost?

Then, we only to find the Xv of equation.

Xv = - b / 2a

Where,

a = 0.25
b = -30

Then ,

Xv = - (-30)/(2×0,25)

Xv = 30 / 0,5

Xv = 60


Hope this helps!
