Good afternoon.

Can anyone help me with the exact calculations for this problem.

The photo shows popular combinations of US dollar serial numbers, as well as the number of notes for 96,000,000 banknotes. The US dollar serial number is 8 digits long.

I need to do the same calculations for banknotes with a seven-digit serial number and a series of 9.999.999.

Please help me figure it out.
