Ian, Hal and Tim had the same number of notes. Ian and Hal had a mix of $10-notes and $5-notes. Ian had 2 $10-notes while Hal had 12 $10-notes. Tim only had $10-notes.
- Who had the least amount of money?
- How much more did Hal have than Ian?
- Hal used all his $5-notes to buy a wallet. He then had $240 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 Ian had the least number of $10-notes, he had the least money.
(b)
Number of more $10-notes that Hal had than Ian
= 12 - 2
= 10
Difference in the value of $10-note and $5-note
= 10 - 5
= $5
Amount that Hal had more than Ian
= 10 x 5
= $50
(c)
Value of $10-notes that Hal had left
= 12 x 10
= $120
Total value that Tim had
= 120 + 240
= $360
Number of $10-notes that Tim had
= 360 ÷ 10
= 36
Answer(s): (a) Ian; (b) $50; (c) 36
