Ken, Jon and Eli had the same number of notes. Ken and Jon had a mix of $50-notes and $5-notes. Jon had 2 $50-notes while Ken had 11 $50-notes. Eli only had $50-notes.
- Who had the least amount of money?
- How much less did Jon have than Ken?
- Ken used all his $5-notes to buy a wallet. He then had $1350 less than Eli. How many $50-notes did Eli have?
(a)
The three boys had the same number of notes.
$50-notes have a higher denomination than $5-notes.
Since Jon had the least number of $50-notes, he had the least money.
(b)
Number of less $50-notes that Jon had than Ken
= 11 - 2
= 9
Difference in the value of $50-note and $5-note
= 50 - 5
= $45
Amount that Jon had less than Ken
= 9 x 45
= $405
(c)
Value of $50-notes that Ken had left
= 11 x 50
= $550
Total value that Eli had
= 550 + 1350
= $1900
Number of $50-notes that Eli had
= 1900 ÷ 50
= 38
Answer(s): (a) Jon; (b) $405; (c) 38
