Eli, Jed and Max had the same number of notes. Eli and Jed had a mix of $100-notes and $50-notes. Jed had 12 $100-notes while Eli had 15 $100-notes. Max only had $100-notes.

1. Who had the least amount of money?
2. How much less did Jed have than Eli?
3. Eli used all his $50-notes to buy a wallet. He then had $1800 less than Max. How many $100-notes did Max have?

(a)
The three boys had the same number of notes.
$100-notes have a higher denomination than $50-notes.

Since Jed had the least number of $100-notes, he had the least money.

(b)
Number of less $100-notes that Jed had than Eli
= 15 - 12
= 3

Difference in the value of $100-note and $50-note
= 100 - 50
= $50

Amount that Jed had less than Eli
= 3 x 50
= $150

(c)
Value of $100-notes that Eli had left
= 15 x 100
= $1500

Total value that Max had
= 1500 + 1800
= $3300

Number of $100-notes that Max had
= 3300 ÷ 100
= 33

Answer(s): (a) Jed; (b) $150; (c) 33
