Answer: $105,000
Explanation: Andrew's taxable income will increase by $105,000.
The ordinary income of $40,000, guaranteed payment of $65,000, and cash distribution of $20,000 are all taxable to Andrew as a partner in the partnership. Therefore, the total amount of taxable income is $40,000 + $65,000 + $20,000 = $125,000.
Therefore, the correct choice is:
$105,000.
