1. Of the three men, who had the least money? 
2. What was the difference in the total value of Rio and Bo's notes? 
3. Bo used all his $100-notes to buy a souvenir. Jim then had $2300 more than Bo. How many $100-notes did Jim have?

(a)
The three men had the same number of notes.
$20-notes have a lower denomination than $100-notes.

Bo had more $20-notes than Rio while Jim had only the $100-notes.  

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

(b)
Difference in the number of notes of different values
= 20 - 14
= 6

Difference in the value of $100-note and $20-note
= 100 - 20
= $80

Difference in the total value of Rio's and Bo's notes
= 6 x 80
= $480

(c)
Value of $20-notes that Bo had left
= 20 x 20
= $400

Total value that Jim had
= 2300 + 400
= $2700

Number of $100-notes that Jim had
= 2700 ÷ 100
= 27

Answer(s): (a) Bo; (b) $480; (c) 27
