On: AT&T raises most customers' fees by $1.23, adding ...

[achille]

> The change is estimated to impact about 85 percent of AT&T's 64.5 million postpaid phone lines in service, making for about $800 million in additional annual revenue.

85% * 64.5 million * $1.23 = 67 million

Where did the other 733 million come from?

Edit: Ah monthly fee; Annual revenue.

$67 million a month * 12 = $804 million. I am assuming it is a monthly increase.

[dokein → achille]

Annual revenue, monthly fee.

[benjaminjackman → achille]

is it monthly? because then the math works:

>>> 0.85 * 64.5 * $1.23 * 12

$809.22
