The cost of producing x units of a product is C dollars, where C is given by the function C = 0.25x² - 80x + 300. What is the cost if no units are produced? A) $0 B) $100 C) $150 D) $300

Just sub zero for x in your function:

C = 0.25x² - 80x + 300

C = 0.25(0)^2 - 80(0) + 300

C = 0 - 0 + 300

C = $300, or D on your list.

Thank you.
