- 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 = 10
Smallest possible amount = 9 are $5 notes and 1 is $100 note
Smallest possible amount
= 9 x 5 + 100 x 1
= $145
(b)
Largest possible amount = 9 are $100 notes and 1 is $5 note
Largest possible amount
= 9 x 100 + 1 x 5
= $905
Answer(s): (a) $145; (b) $905
