Approximately how many pieces of mail were processed by the United States Postal Service in

2006​

Explanation:

Let x represent the number of mails processed in year 2006

Given;

Number of mails processed in 2012 N = 1.6 × 10^11

Number of mails processed in 2012 N is about 75% of the number of pieces of mail processed in 2006.

So;

N = 75% of x

N = 0.75x

x = N/0.75

x = (1.6 × 10^11)/0.75

x = 2.13 × 10^11

Approximately 2.13 × 10^11 mails were processed in 2006
