Don, Hal and Ari had the same number of notes. Don and Hal had a mix of $100-notes and $50-notes. Don had 9 $100-notes while Hal had 13 $100-notes. Ari only had $100-notes.
- Who had the least amount of money?
- How much more did Hal have than Don?
- Hal used all his $50-notes to buy a wallet. He then had $2000 less than Ari. How many $100-notes did Ari have?
(a)
The three boys had the same number of notes.
$100-notes have a higher denomination than $50-notes.
Since Don had the least number of $100-notes, he had the least money.
(b)
Number of more $100-notes that Hal had than Don
= 13 - 9
= 4
Difference in the value of $100-note and $50-note
= 100 - 50
= $50
Amount that Hal had more than Don
= 4 x 50
= $200
(c)
Value of $100-notes that Hal had left
= 13 x 100
= $1300
Total value that Ari had
= 1300 + 2000
= $3300
Number of $100-notes that Ari had
= 3300 ÷ 100
= 33
Answer(s): (a) Don; (b) $200; (c) 33
