According to the Barbie web site, "this one doll is a $1.9 billion a year industry, with two Barbies being bought every second."

What is the average cost of one Barbie, given the information above?

 


Solution to the Problem:

The answer is $30.10.

There are 3,600 seconds x 24 hours x 365.25 days per year = 31,557,600 seconds in an average year.   If two Barbies are sold every second, then 63,115,200 Barbie dolls are sold annually.   This works out to an average cost of 1,900,000,000 / 63,115,200 = $30.10 each.
