Dear all,

Enclosed please find the excel file with the answer to the bank question in our brain stretcher last week. Many thanks to Mr. Zhang (Jason’s dad) for sharing!

Q4: Bank of America has money in the forms of $1, $5, $10, $20 and $100. How many different combinations can Tony withdraw $100 dollars at the counter?

There is no school for the following two weeks, but please feel free to contact me if you have any questions regarding our previous chapters/exercises. I will be very glad to help.

Enjoy the spring break, and I look forward to meeting you all when we are back!

Best,

Lijia
