- 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 $10 notes and 1 is $50 note
Smallest possible amount
= 8 x 10 + 50 x 1
= $130
(b)
Largest possible amount = 8 are $50 notes and 1 is $10 note
Largest possible amount
= 8 x 50 + 1 x 10
= $410
