Answer

Final Answer: The total cost of producing the first 220 dresses is $$ 8228.00$ .

Steps

Step 1 ：The marginal cost function, $C^{'} (x)$ , gives the cost to produce one additional dress. To find the total cost of producing the first 220 dresses, we need to integrate the marginal cost function from 0 to 220. This will give us the total cost of producing 220 dresses.

Step 2 ：Given the marginal cost function $C^{'} (x) = 55 - 0.16 x$ , we can calculate the total cost.

Step 3 ：The total cost of producing the first 220 dresses is calculated to be $8228.00.

Step 4 ：Final Answer: The total cost of producing the first 220 dresses is $$ 8228.00$ .
