HaiGuis in Shanghai can only afford 帶皮方肉

Pork(less fat): 30元 /斤, 帶皮方肉，21.5元/斤

To maintain turtles healthy, 1000g is minimum daily consumtion for a turtle family.

12mon x 30 days x 2 x 30 = 21600

If HaiGui\'s yearly income is as high as 200k after tax, how much percentage does the HaiGui spend for Pork only?
