Abe, Kai and Ike had the same number of notes. Abe and Kai had a mix of $100-notes and $20-notes. Abe had 5 $100-notes while Kai had 12 $100-notes. Ike only had $100-notes.
- Who had the least amount of money?
- How much more did Kai have than Abe?
- Kai used all his $20-notes to buy a wallet. He then had $3800 less than Ike. How many $100-notes did Ike have?
(a)
The three boys had the same number of notes.
$100-notes have a higher denomination than $20-notes.
Since Abe had the least number of $100-notes, he had the least money.
(b)
Number of more $100-notes that Kai had than Abe
= 12 - 5
= 7
Difference in the value of $100-note and $20-note
= 100 - 20
= $80
Amount that Kai had more than Abe
= 7 x 80
= $560
(c)
Value of $100-notes that Kai had left
= 12 x 100
= $1200
Total value that Ike had
= 1200 + 3800
= $5000
Number of $100-notes that Ike had
= 5000 ÷ 100
= 50
Answer(s): (a) Abe; (b) $560; (c) 50
