Accoding to Treasury Secretary John Snow, the United States debt limit currently is $8.18 trillion...and now needs to ask for another limit extension. In 2005, the limit was increased by $781 billion.
Question 1: If the debt limit is increased by the same amount this year, what percent increase is involved?
Question 2: Suppose the debt limit of $8.18 trillion was paid off by an anyomous benefactor. If arranged in a single stack, would the payoff reach from the earth to the moon if paid off in:
- Pennies?
- Nickels?
- Dimes?
- Quarters?
- One Dollar Bills?
- Five Dollar Bills?
- Ten Dollar Bills?
- Twenty Dollar Bills?
- One Hundred Dollar Bills?
If a pile does reach to the moon, is there enough left to build a pile back to earth?
