Please use the safe url below to answer this Supply Chain question in regards to total cost of ownership. I need to verify my approach. Thanks!

In Table 9-3 of the safe URL below, when calculating hourly labor for China, should I add the Textiles value (0.62) and the Clothing value (0.43) and then divide by 2, and if so, why? Wouldn't just adding the values together give me the correct hourly labor cost: 0.62+0.43 = 1.05? Fyi, I am trying to calculate total cost of ownership.
