500 accounts which are
visited six times a year = 3,000 visits totally

3000 visits * 2 hours
each = 6,000 hours of visits

Travel and administration
time = 6,000 hours

Spiro therefore needs
12,000 hours

One salesperson works
40 hours/week * 50 weeks = 2,000 hours

To get 12,000 hours:
12,000/2,000 = 6 salespeople.

The correct answer is b).

14. Spiro Corp. has
found that an effective salesperson should call on each account about six
times a year and spend about two hours per sales call. Every salesperson
works a 40-hour week and takes off two weeks for vacation each year. A
salesperson must spend half of his time on travel and administration. Approximately
how many salespeople does Spiro need to service 500 accounts?

a)
2

b)
6

c)
12

d)
