Tom, Max and Lon had the same number of notes. Tom and Max had a mix of $10-notes and $5-notes. Tom had 7 $10-notes while Max had 16 $10-notes. Lon only had $10-notes.
- Who had the least amount of money?
- How much more did Max have than Tom?
- Max used all his $5-notes to buy a wallet. He then had $240 less than Lon. How many $10-notes did Lon have?
(a)
The three boys had the same number of notes.
$10-notes have a higher denomination than $5-notes.
Since Tom had the least number of $10-notes, he had the least money.
(b)
Number of more $10-notes that Max had than Tom
= 16 - 7
= 9
Difference in the value of $10-note and $5-note
= 10 - 5
= $5
Amount that Max had more than Tom
= 9 x 5
= $45
(c)
Value of $10-notes that Max had left
= 16 x 10
= $160
Total value that Lon had
= 160 + 240
= $400
Number of $10-notes that Lon had
= 400 ÷ 10
= 40
Answer(s): (a) Tom; (b) $45; (c) 40
