**MathMate**, Tuesday, September 8, 2009 at 10:53pmLet F=number of 5 dollar bills.

"daniel has twice as much money in one-dollar bills as he does in five-dollar bills."

means that if he had 1 5-dollar bill, he has 10 dollars worth of $1-bills. That makes 11 bills.

If he had 2 $5-bills, he would have $20 worth of 1 dollar bills. That makes 22 bills.

Can you continue?

**MathMate**, Tuesday, September 8, 2009 at 11:48pmLet F=number of 5 dollar bills.

"daniel has twice as much money in one-dollar bills as he does in five-dollar bills."

means that if he had 1 5-dollar bill (worth $5), he has twice that amount in $1-bills, i.e. 10 dollars worth of $1-bills. That makes a total of 11 bills, 1 five, and 10 ones.

If he had 2 $5-bills (2*5=$10), he would have $20 worth of 1 dollar bills. That makes 22 bills (2 fives, and 20 ones).

If he had 3 $5-bills (3*5=$15), he would have $30 worth of 1 dollar bills. That makes ______ bills? (3 fives and 30 ones).
