[AI-generated answer — Bot GPT 3.5]

A. New mean:

Old mean = (0 + 0 + 0 + 0 + 0 + 0 + 0 + 0 + 200 + 200 + 200 + 200 + 200 + 200 + 200 + 30,600) / 16 = $1,900

New mean = (0 + 0 + 0 + 0 + 0 + 0 + 0 + 0 + 200 + 200 + 200 + 200 + 200 + 200 + 200 + 30,600 + 200 + 200 + 200 + 200) / 20 = $2,050

B. New Median:

Old median = $200

New median = The 10th and 11th values in the ordered list of incomes are the two middle values, which are both $200, so the new median is still $200.

C. New Mode:

Old mode = $200

New mode = The most frequently occurring value in the list is still $200, so the new mode is still $200.
