Lee, Sam and Ian had the same number of notes. Lee and Sam had a mix of $100-notes and $20-notes. Sam had 4 $100-notes while Lee had 10 $100-notes. Ian only had $100-notes.
- Who had the least amount of money?
- How much less did Sam have than Lee?
- Lee used all his $20-notes to buy a wallet. He then had $3500 less than Ian. How many $100-notes did Ian have?
(a)
The three boys had the same number of notes.
$100-notes have a higher denomination than $20-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 Lee
= 10 - 4
= 6
Difference in the value of $100-note and $20-note
= 100 - 20
= $80
Amount that Sam had less than Lee
= 6 x 80
= $480
(c)
Value of $100-notes that Lee had left
= 10 x 100
= $1000
Total value that Ian had
= 1000 + 3500
= $4500
Number of $100-notes that Ian had
= 4500 ÷ 100
= 45
Answer(s): (a) Sam; (b) $480; (c) 45
