The total cost in thousands of dollars of manufacturing x cell phones is given by the cost function C(x) = 0.018x + 1000. Find the total cost (in thousands of dollars) of manufacturing 900 cell phones. Do not use commas or spaces in your answer. For example, if your answer is 1,536.45 thousands of dollars then input only 1536.45. Answer: K
