Rio, Eli and Tim had the same number of notes. Rio and Eli had a mix of $10-notes and $5-notes. Rio had 10 $10-notes while Eli had 19 $10-notes. Tim only had $10-notes.
- Who had the least amount of money?
- How much more did Eli have than Rio?
- Eli used all his $5-notes to buy a wallet. He then had $180 less than Tim. How many $10-notes did Tim have?
(a)
The three boys had the same number of notes.
$10-notes have a higher denomination than $5-notes.
Since Rio had the least number of $10-notes, he had the least money.
(b)
Number of more $10-notes that Eli had than Rio
= 19 - 10
= 9
Difference in the value of $10-note and $5-note
= 10 - 5
= $5
Amount that Eli had more than Rio
= 9 x 5
= $45
(c)
Value of $10-notes that Eli had left
= 19 x 10
= $190
Total value that Tim had
= 190 + 180
= $370
Number of $10-notes that Tim had
= 370 ÷ 10
= 37
Answer(s): (a) Rio; (b) $45; (c) 37
