Answer:
a) 29,000
b) 44,000
c) -26,000 (loss)
d) 9,000 gain
Explanation:
Net income will be the difference in equity plus dividends less contributions.

To sovle for this we use the accouting equation:
assets = laibilities + equity
the beginning and ending equity is the same for all years:
60,000 = 20,000 + equity
equity = 40,000
ending equity: 105,000 - 36,000 = 69,000
what changes is the value for dividend and contribution
a)
income: 69,000 - 40,000 + 0 - 0 = 29,000
b) 69,000 - 40,000 + 1,250 x 12 - 0 = 44,000
c) 69,000 - 40,000 + 0 - 55,000 = -26,000
d) 69,000 - 40,000 + 1,250 x 12 - 35,000 = 9,000
