I'm sort of guessing sort of not on this one:
There are 300,000,000 people in America (as of earlier this year). If an adult is anybody over 18, and the average life span is around 80, then (80-18) / 80 is the percent of adults in any given population = 77.5% I'm gonna round down to 75% since it makes sense that the child to adult ratio is getting bigger, so take .75 * 300,000,000 and you get 225,000,000 adults. Now multiply by .04 to get 9 million adults.

.04 x 300,000,000 = 12 million.
