- What could be the largest possible amount of money she had in her handbag?
(a)
Total number of notes = 10
Smallest possible amount = 9 are $5 notes and 1 is $10 note
Smallest possible amount
= 9 x 5 + 10 x 1
= $55
(b)
Largest possible amount = 9 are $10 notes and 1 is $5 note
Largest possible amount
= 9 x 10 + 1 x 5
= $95
Answer(s): (a) $55; (b) $95
