1. Of the three men, who had the least money? 
2. What was the difference in the total value of Tim and Jed's notes? 
3. Jed used all his $100-notes to buy a present. Ben then had $2540 more than Jed. How many $100-notes did Ben have?

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

Jed had more $20-notes than Tim while Ben had only the $100-notes.  

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

(b)
Difference in the number of notes of different values
= 23 - 14
= 9

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

Difference in the total value of Tim's and Jed's notes
= 9 x 80
= $720

(c)
Value of $20-notes that Jed had left
= 23 x 20
= $460

Total value that Ben had
= 2540 + 460
= $3000

Number of $100-notes that Ben had
= 3000 ÷ 100
= 30

Answer(s): (a) Jed; (b) $720; (c) 30
