Answer: $900
Step-by-step explanation:
The Total Capital of the company before Zell was admitted was;
= Capital balances + Goodwill
= 600 + 800 + 700
= $2,100
If they admitted Zell in with a 30% interest, this means that the $2,100 is equivalent to 70% of the company's capital.
If that is the case then Total capital is;
= 2,100/ 70%
= $3,000
Zell's contribution is;
= 30% * 3,000
= $900
