This question is in reference to 2 scenarios. The partners are Drury and Wilkins who initially invested $87,600 and $21,900. Salary allowances are $74,400 and $37,200. Interest allowance is 10% and Drury is also to be allowed a bonus equal to 20% of the amount by which net income exceeds the salary allowances. The two income scenarios are $328,500 and $144,6000. I understand the Sal allow, interest allow, and calculating bonus; however, I am unsure how to calculate excess where income is more than totals. Below is chart of information for two scenarios.
