Jane has $50 in her wallet. The bills are worth either $5 or $1. There are 18 bills total.

Bosnian says Jane has 6 five dollar bills and 10 one dollar bills.
Manny says Jane has 8 five dollar bills and 10 one dollar bills.

1 answer

Let's verify the claims made by Bosnian and Manny about the bills that Jane has.

Let:

  • \( x \) be the number of $5 bills.
  • \( y \) be the number of $1 bills.

From the problem, we know three pieces of information:

  1. The total number of bills is 18. \[ x + y = 18 \]

  2. The total amount of money is $50. \[ 5x + 1y = 50 \]

We can now analyze each person's claim to see if either of them is correct.

Bosnian's Claim:

Bosnian claims Jane has 6 five dollar bills and 10 one dollar bills.

  • Here, \( x = 6 \) and \( y = 10 \).

Let's check if this satisfies our equations:

  1. Total number of bills: \[ x + y = 6 + 10 = 16 \quad (\text{not } 18) \] Thus, Bosnian's claim is not correct.

Manny's Claim:

Manny claims Jane has 8 five dollar bills and 10 one dollar bills.

  • Here, \( x = 8 \) and \( y = 10 \).

Now, let's check this:

  1. Total number of bills: \[ x + y = 8 + 10 = 18 \quad (\text{correct}) \]

  2. Total amount of money: \[ 5x + 1y = 5(8) + 1(10) = 40 + 10 = 50 \quad (\text{correct}) \]

Since both conditions are satisfied for Manny's claim, Manny's assertion is correct.

Conclusion:

Jane has 8 five dollar bills and 10 one dollar bills. Bosnian's claim is incorrect while Manny's claim is correct.
