- What could be the largest possible amount of money she had in her handbag?
(a)
Total number of notes = 8
Smallest possible amount = 7 are $10 notes and 1 is $100 note
Smallest possible amount
= 7 x 10 + 100 x 1
= $170
(b)
Largest possible amount = 7 are $100 notes and 1 is $10 note
Largest possible amount
= 7 x 100 + 1 x 10
= $710
Answer(s): (a) $170; (b) $710
