Ken, Sam and Bo had the same number of notes. Ken and Sam had a mix of $100-notes and $5-notes. Sam had 10 $100-notes while Ken had 14 $100-notes. Bo only had $100-notes.
- Who had the least amount of money?
- How much less did Sam have than Ken?
- Ken used all his $5-notes to buy a wallet. He then had $2800 less than Bo. How many $100-notes did Bo have?
(a)
The three boys had the same number of notes.
$100-notes have a higher denomination than $5-notes.
Since Sam had the least number of $100-notes, he had the least money.
(b)
Number of less $100-notes that Sam had than Ken
= 14 - 10
= 4
Difference in the value of $100-note and $5-note
= 100 - 5
= $95
Amount that Sam had less than Ken
= 4 x 95
= $380
(c)
Value of $100-notes that Ken had left
= 14 x 100
= $1400
Total value that Bo had
= 1400 + 2800
= $4200
Number of $100-notes that Bo had
= 4200 ÷ 100
= 42
Answer(s): (a) Sam; (b) $380; (c) 42
