Final Answer: The total cost, in dollars, of producing 550 cards is \(\boxed{93.5}\). However, this option is not available in the given choices. There might be a mistake in the problem or in my calculations.

Steps

Step 1 :The cost per card is given by the derivative of the cost function, \(C^{\prime}(x)=-0.06 x+50\).

Step 2 :To find the total cost of producing 550 cards, we need to evaluate this function at \(x=550\) and then multiply by the number of cards, 550.

Step 3 :The cost per card is \(17.0\) cents.

Step 4 :The total cost in cents is \(9350.0\) cents.

Step 5 :Since the cost is given in cents, we need to convert it to dollars by dividing by 100.

Step 6 :The total cost in dollars is \(93.5\) dollars.

Step 7 :Final Answer: The total cost, in dollars, of producing 550 cards is \(\boxed{93.5}\). However, this option is not available in the given choices. There might be a mistake in the problem or in my calculations.
