Rio, Bo and Ian had the same number of notes. Rio and Bo had a mix of $100-notes and $50-notes. Rio had 9 $100-notes while Bo had 14 $100-notes. Ian only had $100-notes.
- Who had the least amount of money?
- How much more did Bo have than Rio?
- Bo used all his $50-notes to buy a wallet. He then had $3300 less than Ian. How many $100-notes did Ian have?
(a)
The three boys had the same number of notes.
$100-notes have a higher denomination than $50-notes.
Since Rio had the least number of $100-notes, he had the least money.
(b)
Number of more $100-notes that Bo had than Rio
= 14 - 9
= 5
Difference in the value of $100-note and $50-note
= 100 - 50
= $50
Amount that Bo had more than Rio
= 5 x 50
= $250
(c)
Value of $100-notes that Bo had left
= 14 x 100
= $1400
Total value that Ian had
= 1400 + 3300
= $4700
Number of $100-notes that Ian had
= 4700 ÷ 100
= 47
Answer(s): (a) Rio; (b) $250; (c) 47
