Question

A bank randomly surveyed 50 of its customers by mail to find out how customers use its mobile banking service. The survey found that only 11 of the 50 customers used the service.

If the branch has 1,700 customers, about     A. 374   B.663   C. 1,037   D.1,326   customers use the mobile banking service.

Answer 1

11/50 = 0.22 
I'm assuming the question is asking what number/1700 = 0.22
So, 374/1700 = 0.22
Answer is A

Answer 2

Hello there! :D

I did 11/50= 0.22. Then I multiplied the 0.22*1700= 374.

Therefore the answer is A!

Hope it helps! :D ;)
