Question 1140632
A after a month is 4000(4)+0.145*40000=16000+5800=21,800 in a month.  After six months, 26 weekly salaries are 104,000+ .145*200000=29000=133,000

B straight commission of 30% gives 12,000 in first month and 60000 at the end of six months.  Given that the weekly salary is significant, it is not surprising that A pays better.

If A is a monthly salary of 4000, then it would be 9800 in the first month and 53,000 after six months and then B would be better.
