Nat, Tom and Rio had the same number of notes. Nat and Tom had a mix of $50-notes and $5-notes. Nat had 13 $50-notes while Tom had 18 $50-notes. Rio only had $50-notes.
- Who had the least amount of money?
- How much more did Tom have than Nat?
- Tom used all his $5-notes to buy a wallet. He then had $1100 less than Rio. How many $50-notes did Rio have?
(a)
The three boys had the same number of notes.
$50-notes have a higher denomination than $5-notes.
Since Nat had the least number of $50-notes, he had the least money.
(b)
Number of more $50-notes that Tom had than Nat
= 18 - 13
= 5
Difference in the value of $50-note and $5-note
= 50 - 5
= $45
Amount that Tom had more than Nat
= 5 x 45
= $225
(c)
Value of $50-notes that Tom had left
= 18 x 50
= $900
Total value that Rio had
= 900 + 1100
= $2000
Number of $50-notes that Rio had
= 2000 ÷ 50
= 40
Answer(s): (a) Nat; (b) $225; (c) 40
