Let Nellie = 2 units, Brother = 3 units (since Nellie has \(\frac{2}{3}\) of brother's money).

• Brother − Nellie = 3 units − 2 units = 1 unit
• 1 unit → $14
• Nellie = 2 units = 2 × $14 = $28

Note: The stored answer is $21, which would require Nellie = \(\frac{3}{5}\) of her brother's money. With the given fraction \(\frac{2}{3}\), the correct answer is $28.

Final Answer: $28
