- 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 = 11
Smallest possible amount = 10 are $5 notes and 1 is $50 note
Smallest possible amount
= 10 x 5 + 50 x 1
= $100
(b)
Largest possible amount = 10 are $50 notes and 1 is $5 note
Largest possible amount
= 10 x 50 + 1 x 5
= $505
Answer(s): (a) $100; (b) $505
