- 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 = 15
Smallest possible amount = 14 are $5 notes and 1 is $10 note
Smallest possible amount
= 14 x 5 + 10 x 1
= $80
(b)
Largest possible amount = 14 are $10 notes and 1 is $5 note
Largest possible amount
= 14 x 10 + 1 x 5
= $145
Answer(s): (a) $80; (b) $145
