Question

HELP 50 POINTS!!!!

Answer 1

The minimum cost y = $78. 

 
x = 12 cakes to yield minimum cost.

Answer 2

1) y = 0.5x^2 - 12x + 150 axis of symmetry x = -b/(2a) x = 12/1 = 12 y = 0.5(x^2 - 24x + 144) - 72 + 150 y = 0.5(x - 12)^2 + 78 vertex = (12, 78) 2) The vertex is the minimum point, and the minimum cost y = $78. 3) x = 12 cakes to yield minimum cost.
