In 2005, the population of a certain country was about 255.4 million. to the nearest dollar, calculate how much each person in the country would have had to contribute in order to make one lucky person a trillionaire (that is, to give that person $ 1,000,000,000,000) each person would have to contribute how much $?

$3915.43

Step-by-step explanation:

In scientific notation the amount is computed by dividing 1 trillion into 255.4 million parts. Each part is ...

  $10^12/(0.2554·10^9) = $3.91543·10^3 = $3915.43

Each person would have to contribute about $3,915.43.

Comment on the division

I like to adjust the operands in the math expression so the result comes out in scientific notation. To that end, I have made the denominator be a fraction less than 1 (times 10 to a power), rather than the usual number between 1 and 10. This ensures that the quotient will be between 1 and 10 (times 10 to some power).

a'(12.5,11.25)

slope=(y1-y2)/(x1-x2)
