Rey, Roy and Jim had the same number of notes. Rey and Roy had a mix of $100-notes and $50-notes. Rey had 8 $100-notes while Roy had 15 $100-notes. Jim only had $100-notes.
- Who had the least amount of money?
- How much more did Roy have than Rey?
- Roy used all his $50-notes to buy a wallet. He then had $3200 less than Jim. How many $100-notes did Jim have?
(a)
The three boys had the same number of notes.
$100-notes have a higher denomination than $50-notes.
Since Rey had the least number of $100-notes, he had the least money.
(b)
Number of more $100-notes that Roy had than Rey
= 15 - 8
= 7
Difference in the value of $100-note and $50-note
= 100 - 50
= $50
Amount that Roy had more than Rey
= 7 x 50
= $350
(c)
Value of $100-notes that Roy had left
= 15 x 100
= $1500
Total value that Jim had
= 1500 + 3200
= $4700
Number of $100-notes that Jim had
= 4700 ÷ 100
= 47
Answer(s): (a) Rey; (b) $350; (c) 47
