1. Of the three boys, who had the most money? 
2. What was the difference in the total value of Eli and Tim's notes? 
3. Tim used all his $10-notes to buy a gift. He then had $226 less than Ben. How many $10-notes did Ben have?

(a)
The three boys had the same number of notes.
$2-notes have a lower denomination than $10-notes.

Since Ben had only $10-notes, he had the most money.

(b)
Difference in the number of notes of different values
= 12 - 6
= 6

Difference in the value of $10-notes and $2-notes
= 10 - 2
= $8

Difference in the total value of Eli's and Tim's notes
= 6 x 8
= $48

(c)
Value of $2-notes that Tim had left
= 12 x 2
= $24

Total value that Ben had
= 226 + 24
= $250

Number of $10-notes that Ben had
= 250 ÷ 10
= 25

Answer(s): (a) Ben; (b) $48; (c) 25
