- What could be the smallest possible amount of money she had in her handbag?
- What could be the largest possible amount of money she had in her handbag?
(a)
Total number of notes = 9
Smallest possible amount = 8 are $5 notes and 1 is $10 note
Smallest possible amount
= 8 x 5 + 10 x 1
= $50
(b)
Largest possible amount = 8 are $10 notes and 1 is $5 note
Largest possible amount
= 8 x 10 + 1 x 5
= $85
Answer(s): (a) $50; (b) $85
