Ray, Hal and Ty had the same number of notes. Ray and Hal had a mix of $100-notes and $20-notes. Ray had 14 $100-notes while Hal had 20 $100-notes. Ty only had $100-notes.
- Who had the least amount of money?
- How much more did Hal have than Ray?
- Hal used all his $20-notes to buy a wallet. He then had $2100 less than Ty. How many $100-notes did Ty have?
(a)
The three boys had the same number of notes.
$100-notes have a higher denomination than $20-notes.
Since Ray had the least number of $100-notes, he had the least money.
(b)
Number of more $100-notes that Hal had than Ray
= 20 - 14
= 6
Difference in the value of $100-note and $20-note
= 100 - 20
= $80
Amount that Hal had more than Ray
= 6 x 80
= $480
(c)
Value of $100-notes that Hal had left
= 20 x 100
= $2000
Total value that Ty had
= 2000 + 2100
= $4100
Number of $100-notes that Ty had
= 4100 ÷ 100
= 41
Answer(s): (a) Ray; (b) $480; (c) 41
