Dan, Gus and Jim had the same number of notes. Dan and Gus had a mix of $20-notes and $5-notes. Dan had 14 $20-notes while Gus had 20 $20-notes. Jim only had $20-notes.

1. Who had the least amount of money?
2. How much more did Gus have than Dan?
3. Gus used all his $5-notes to buy a wallet. He then had $200 less than Jim. How many $20-notes did Jim have?

(a)
The three boys had the same number of notes.
$20-notes have a higher denomination than $5-notes.

Since Dan had the least number of $20-notes, he had the least money.

(b)
Number of more $20-notes that Gus had than Dan
= 20 - 14
= 6

Difference in the value of $20-note and $5-note
= 20 - 5
= $15

Amount that Gus had more than Dan
= 6 x 15
= $90

(c)
Value of $20-notes that Gus had left
= 20 x 20
= $400

Total value that Jim had
= 400 + 200
= $600

Number of $20-notes that Jim had
= 600 ÷ 20
= 30

Answer(s): (a) Dan; (b) $90; (c) 30
