Lizzy: Marly has ten $20 bills, eight $10 bills, and four $5 bills. If she wants to change her bills to $100 bills, how many pieces of $100 bills will she have?.
Me: Hmmm, let me think. I think this is the detailed solution:

The ten $20 bills amount to $20 x 10 = $200. The eight $10 bills amount to $10 x 8 = $80. The four $5 bills amount to $5 x 4 = $20. So, Marly has a total of $200 + $80 + $20 = $300. Therefore, she will have $300 / $100 = 3 pieces of $100 bills. Final answer: 3.
