- What could be the smallest possible amount of money she had in her wallet?
- What could be the largest possible amount of money she had in her wallet?
(a)
Total number of notes = 9
Smallest possible amount = 8 are $2 notes and 1 is $100 note
Smallest possible amount
= 8 x 2 + 100 x 1
= $116
(b)
Largest possible amount = 8 are $100 notes and 1 is $2 note
Largest possible amount
= 8 x 100 + 1 x 2
= $802
Answer(s): (a) $116; (b) $802
