Atelemarketing company calls telephone numbers chosen at random. it finds that 30% of calls are not completed (the party does not answer or refuses to talk), that 40% result in talking to a woman, and that 30% result in talking to a man. after that point, 45% of the women and 40% of the men actually buy something. what percent of calls result in a sale?

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 =

Out of 21 males 40% buy something =

Total percent of calls result in a sale =

So 21% of calls result in a sale

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

9 x 8 divided by (5-3)=36
