daniel has twice as much money in one-dollar bills as he does in five-dollar bills. he has 33 bills in all (all one-dollar and five-dollar bills). how much money does he have?

• math -

Let
F=number of five dollar bills,
then
number of one-dollar bills = (5*F)*2
Total number of bills
33 = (5*F)*2 + F
Can you complete the solution?

Let 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?

no i am still a little confused

Let 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).
