Total amount of money if all the notes are ten-dollar notes
= 14 x 10
= $140
Big difference between the amounts of ten-dollar notes and two-dollar notes
= 140 - 92
= $48
Small difference between amount in one ten-dollar note and one two-dollar note
= 10 - 2
= 8
Number of two-dollar notes
= 48 ÷ 8
= 6
Number of ten-dollar notes
= 14 - 6
= 8
