70 is the answer I am pretty sure
Answer:
1/2
Step-by-step explanation:
y=1/2x
1/2 is constant
1/2y+y²
2(1/2y)+y²*2
y+2y²
y+4y
5y
Answer:
$15,339
Step-by-step explanation:
C(x) = 0.5x² − 100x + 20,339
Since this is a parabola, the minimum cost is at the vertex:
x = -b / (2a)
x = -(-100) / (2 × 0.5)
x = 100
So the minimum cost is:
C(100) = 0.5(100)² − 100(100) + 20,339
C(100) = 15,339
