Asa, Ned and Hal had the same number of notes. Asa and Ned had a mix of $50-notes and $10-notes. Ned had 10 $50-notes while Asa had 13 $50-notes. Hal only had $50-notes.

1. Who had the least amount of money?
2. How much less did Ned have than Asa?
3. Asa used all his $10-notes to buy a wallet. He then had $1350 less than Hal. How many $50-notes did Hal have?

(a)
The three boys had the same number of notes.
$50-notes have a higher denomination than $10-notes.

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

(b)
Number of less $50-notes that Ned had than Asa
= 13 - 10
= 3

Difference in the value of $50-note and $10-note
= 50 - 10
= $40

Amount that Ned had less than Asa
= 3 x 40
= $120

(c)
Value of $50-notes that Asa had left
= 13 x 50
= $650

Total value that Hal had
= 650 + 1350
= $2000

Number of $50-notes that Hal had
= 2000 ÷ 50
= 40

Answer(s): (a) Ned; (b) $120; (c) 40
