Tom, Ari and Gus had the same number of notes. Tom and Ari had a mix of $50-notes and $10-notes. Ari had 8 $50-notes while Tom had 14 $50-notes. Gus only had $50-notes.

1. Who had the least amount of money?
2. How much less did Ari have than Tom?
3. Tom used all his $10-notes to buy a wallet. He then had $800 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 $10-notes.

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

(b)
Number of less $50-notes that Ari had than Tom
= 14 - 8
= 6

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

Amount that Ari had less than Tom
= 6 x 40
= $240

(c)
Value of $50-notes that Tom had left
= 14 x 50
= $700

Total value that Gus had
= 700 + 800
= $1500

Number of $50-notes that Gus had
= 1500 ÷ 50
= 30

Answer(s): (a) Ari; (b) $240; (c) 30
