Ken, Rio and Jed had the same number of notes. Ken and Rio had a mix of $100-notes and $50-notes. Ken had 3 $100-notes while Rio had 11 $100-notes. Jed only had $100-notes.
- Who had the least amount of money?
- How much more did Rio have than Ken?
- Rio used all his $50-notes to buy a wallet. He then had $3800 less than Jed. How many $100-notes did Jed have?
(a)
The three boys had the same number of notes.
$100-notes have a higher denomination than $50-notes.
Since Ken had the least number of $100-notes, he had the least money.
(b)
Number of more $100-notes that Rio had than Ken
= 11 - 3
= 8
Difference in the value of $100-note and $50-note
= 100 - 50
= $50
Amount that Rio had more than Ken
= 8 x 50
= $400
(c)
Value of $100-notes that Rio had left
= 11 x 100
= $1100
Total value that Jed had
= 1100 + 3800
= $4900
Number of $100-notes that Jed had
= 4900 ÷ 100
= 49
Answer(s): (a) Ken; (b) $400; (c) 49
