1. Of the three men, who had the least money? 
2. What was the difference in the total value of Abe and Tom's notes? 
3. Tom used all his $100-notes to buy a souvenir. Kit then had $2760 more than Tom. How many $100-notes did Kit have?

(a)
The three men had the same number of notes.
$10-notes have a lower denomination than $100-notes.

Tom had more $10-notes than Abe while Kit had only the $100-notes.  

Since Tom had the most number of $10-notes, he had the least money.

(b)
Difference in the number of notes of different values
= 24 - 6
= 18

Difference in the value of $100-note and $10-note
= 100 - 10
= $90

Difference in the total value of Abe's and Tom's notes
= 18 x 90
= $1620

(c)
Value of $10-notes that Tom had left
= 24 x 10
= $240

Total value that Kit had
= 2760 + 240
= $3000

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

Answer(s): (a) Tom; (b) $1620; (c) 30
