Answer:
C. $ 30,000
Step-by-step explanation:
The total amount Erin paid = $ 33000 + $ 9000
= $ 42000
for a one-fifth stake in the partnership, the capital increases to:
5* 42000 = $ 210000
the land account increased by = final capital - initial capital
= $ 210000 - ($ 140000 + $ 40000)
= $ 30000
Therefore, the land account increased by $ 30000.
