Final answer:
The total amount of salary Abbott and Costello would show on their income distribution is the sum of Abbott's $90,000 salary and Costello's $150,000 salary, equaling $240,000.
Step-by-step explanation:
The partners' salary shown on their income distribution is the total of their drawn salaries - not the amounts they withdrew from the partnership (drawings). In this case, Abbott has a salary of $90,000 per year and Costello has a salary of $150,000 per year. Therefore, the total amount of salary they would show on their income distribution is the sum of both their salaries: $90,000 (Abbott's salary) + $150,000 (Costello's salary) = $240,000.
