You are interviewing three people for one sales job. On the basis of your experience, you believe Jane can sell 600 units a day, Tom can sell 450 units a day and Kevin can sell 400 units a day. The daily salary each person is requesting is as follows: Jane: $200, Tom, $150; Kevin, $100. How would you rank the three applicants?


My working:

If I try to find the amount earned from 1 unit :
Jane = 200/600= $0.33
Tom = 150/450= $0.33
Kevin = 100/400 = $0.25

Ranking: Jane, Tom, Kevin

Is this right?

Why Jane over Tom if the unit cost is the same ?
