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?

    no i still need your help, please

    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?

    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).
