a manufacturer of lighting fixtures has daily production costs modeled by y=.25x2 -10x+800 where y is the total costs in dollars and x is the number of fixtured produced
what is the minimum daily production cost, y?
+36916 Minimum point of the parabola will be given by
-b/2a 10/.5 = 20 fixtures = x
.25 (20)^2 -10(20)+800 = $ 700
