Write a simplified expression for C(x).

A. C(x) = -0.022x^3 + 9000x

B. C(x) = -0.018x^3 + 9000x

C. C(x) = -0.022x^3 + 15,000x

Respuesta :

Answer:

B

Step-by-step explanation:

C(x) = (12,000x - 0.02x^3) - (3000x - 0.002x^3)

C(x) = 12,000x - 0.02x^3 - 3000)x + 0.002x^3

C(x) = (12,000 - 3,000)x + (-0.02 - 0.002)x^3

= 9000x - 0.018x^3
