1. Of the three men, who had the least money? 
2. What was the difference in the total value of Hal and Ike's notes? 
3. Ike used all his $50-notes to buy a present. Tom then had $880 more than Ike. How many $50-notes did Tom have?

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

Ike had more $20-notes than Hal while Tom had only the $50-notes.  

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

(b)
Difference in the number of notes of different values
= 16 - 2
= 14

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

Difference in the total value of Hal's and Ike's notes
= 14 x 30
= $420

(c)
Value of $20-notes that Ike had left
= 16 x 20
= $320

Total value that Tom had
= 880 + 320
= $1200

Number of $50-notes that Tom had
= 1200 ÷ 50
= 24

Answer(s): (a) Ike; (b) $420; (c) 24
