Jed, Gus and Ike had the same number of notes. Jed and Gus had a mix of $20-notes and $5-notes. Jed had 10 $20-notes while Gus had 17 $20-notes. Ike only had $20-notes.
- Who had the least amount of money?
- How much more did Gus have than Jed?
- Gus used all his $5-notes to buy a wallet. He then had $480 less than Ike. How many $20-notes did Ike have?
(a)
The three boys had the same number of notes.
$20-notes have a higher denomination than $5-notes.
Since Jed had the least number of $20-notes, he had the least money.
(b)
Number of more $20-notes that Gus had than Jed
= 17 - 10
= 7
Difference in the value of $20-note and $5-note
= 20 - 5
= $15
Amount that Gus had more than Jed
= 7 x 15
= $105
(c)
Value of $20-notes that Gus had left
= 17 x 20
= $340
Total value that Ike had
= 340 + 480
= $820
Number of $20-notes that Ike had
= 820 ÷ 20
= 41
Answer(s): (a) Jed; (b) $105; (c) 41
