cupoosta [38]

Answer:

21%

Step-by-step explanation:

Actually there are three levels of process here.

If 100 calls are made only 70 calls are completed (since 30%not completed)

Out of these 70 completed we find that 40% i.e. 28 calls to a woman and 30% i.e. 21 go to a man.

28 females and 21 males

Out of 28 females 45% buy something =0.45*28=12.6

Out of 21 males 40% buy something = 0.4*21=8.4

Total percent of calls result in a sale = 12.6+8.4=21

So 21% of calls result in a sale
