You send out 20,000 emails of 6% are opened of those 9% clicked on the link to register for something of those who clicked on the link 30% complete the registration how many people completed the registration

Rounding to the next whole, 33 persons completed the registration

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Number of e-mails sent out = 20,000

Number of e-mails opened = 6%

Number of e-mails that clicked on the link to register = 9% of the 6%

Number of e-mails that completed the registration = 30% of 9% of 6%

2.  How many people completed the registration?

Let's do all the calculations to answer the question, this way:

Number of e-mails opened = 6 % of 20,000

Number of e-mails opened =0.06 * 20,000 = 1,200

Number of e-mails that clicked on the link to register = 9% of the 6%

Number of e-mails that clicked on the link to register = 0.09 * 1,200 = 108

Number of e-mails that completed the registration = 30% of 9% of 6%

Number of e-mails that completed the registration = 0.3 * 108 = 32.4

Rounding to the next whole, 33 persons completed the registration
