Answer:
x = 100 units
Step-by-step explanation:
C = 2.5x^2 + 75x + 25000
To find average cost per unit, divide C by x:
C/x or Average cost (AC) per unit =
= 2.5x + 75 + 25000/x ⇔ 2.5x + 75 + 25000x^-1 (equation 1)
To find cost minimising, we use differentiation (differentiate equation 1 in respect to x and set it equal to 0):
d(AC)/dx = 0
d(AC)/dx ⇔ 2.5 - 25000x^-2 = 0
2.5 = 25000x^-2
2.5 = ![\frac{25000}{x^2}](https://tex.z-dn.net/?f=%5Cfrac%7B25000%7D%7Bx%5E2%7D)
2.5x^2 = 25000
x^2 = 10000
x = ![\sqrt{10000}](https://tex.z-dn.net/?f=%5Csqrt%7B10000%7D)
x = 100 units
The answer would be 80. You would do 44 times 100, then divide by 55.
