1. Of the three men, who had the least money? 
2. What was the difference in the total value of Max and Dan's notes? 
3. Dan used all his $50-notes to buy a present. Sam then had $1210 more than Dan. How many $50-notes did Sam have?

(a)
The three men had the same number of notes.
$10-notes have a lower denomination than $50-notes.

Dan had more $10-notes than Max while Sam had only the $50-notes.  

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

(b)
Difference in the number of notes of different values
= 14 - 2
= 12

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

Difference in the total value of Max's and Dan's notes
= 12 x 40
= $480

(c)
Value of $10-notes that Dan had left
= 14 x 10
= $140

Total value that Sam had
= 1210 + 140
= $1350

Number of $50-notes that Sam had
= 1350 ÷ 50
= 27

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