Nat, Hal and Luc had the same number of notes. Nat and Hal had a mix of $20-notes and $5-notes. Nat had 4 $20-notes while Hal had 14 $20-notes. Luc only had $20-notes.

1. Who had the least amount of money?
2. How much more did Hal have than Nat?
3. Hal used all his $5-notes to buy a wallet. He then had $540 less than Luc. How many $20-notes did Luc have?

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

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

(b)
Number of more $20-notes that Hal had than Nat
= 14 - 4
= 10

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

Amount that Hal had more than Nat
= 10 x 15
= $150

(c)
Value of $20-notes that Hal had left
= 14 x 20
= $280

Total value that Luc had
= 280 + 540
= $820

Number of $20-notes that Luc had
= 820 ÷ 20
= 41

Answer(s): (a) Nat; (b) $150; (c) 41
