Ben, Ty and Gus had the same number of notes. Ben and Ty had a mix of $50-notes and $20-notes. Ben had 2 $50-notes while Ty had 12 $50-notes. Gus only had $50-notes.

1. Who had the least amount of money?
2. How much more did Ty have than Ben?
3. Ty used all his $20-notes to buy a wallet. He then had $1800 less than Gus. How many $50-notes did Gus have?

(a)
The three boys had the same number of notes.
$50-notes have a higher denomination than $20-notes.

Since Ben had the least number of $50-notes, he had the least money.

(b)
Number of more $50-notes that Ty had than Ben
= 12 - 2
= 10

Difference in the value of $50-note and $20-note
= 50 - 20
= $30

Amount that Ty had more than Ben
= 10 x 30
= $300

(c)
Value of $50-notes that Ty had left
= 12 x 50
= $600

Total value that Gus had
= 600 + 1800
= $2400

Number of $50-notes that Gus had
= 2400 ÷ 50
= 48

Answer(s): (a) Ben; (b) $300; (c) 48
