Anna had a total of 7 notes in her jar. They were $10 and $50 notes.
- What could be the smallest possible amount of money she had in her jar?
- What could be the largest possible amount of money she had in her jar?
(a)
Total number of notes = 7
Smallest possible amount = 6 are $10 notes and 1 is $50 note
Smallest possible amount
= 6 x 10 + 50 x 1
= $110
(b)
Largest possible amount = 6 are $50 notes and 1 is $10 note
Largest possible amount
= 6 x 50 + 1 x 10
= $310
Answer(s): (a) $110; (b) $310
