Three boys, Max, Dan and Ike had the same number of notes. Max and Dan each had of mix of $5-notes and $2-notes. Max had 8 $2-notes while Dan had 18 $2-notes. Ike had only $5-notes.

1. Of the three boys, who had the most money? 
2. What was the difference in the total value of Max and Dan's notes? 
3. Dan used all his $5-notes to buy a present. He then had $94 less than Ike. How many $5-notes did Ike have?

(a)
The three boys had the same number of notes.
$2-notes have a lower denomination than $5-notes.

Since Ike had only $5-notes, he had the most money.

(b)
Difference in the number of notes of different values
= 18 - 8
= 10

Difference in the value of $5-notes and $2-notes
= 5 - 2
= $3

Difference in the total value of Max's and Dan's notes
= 10 x 3
= $30

(c)
Value of $2-notes that Dan had left
= 18 x 2
= $36

Total value that Ike had
= 94 + 36
= $130

Number of $5-notes that Ike had
= 130 ÷ 5
= 26

Answer(s): (a) Ike; (b) $30; (c) 26
