Don, Ike and Rey had the same number of notes. Don and Ike had a mix of $100-notes and $50-notes. Ike had 6 $100-notes while Don had 10 $100-notes. Rey only had $100-notes.
- Who had the least amount of money?
- How much less did Ike have than Don?
- Don used all his $50-notes to buy a wallet. He then had $3900 less than Rey. How many $100-notes did Rey have?
(a)
The three boys had the same number of notes.
$100-notes have a higher denomination than $50-notes.
Since Ike had the least number of $100-notes, he had the least money.
(b)
Number of less $100-notes that Ike had than Don
= 10 - 6
= 4
Difference in the value of $100-note and $50-note
= 100 - 50
= $50
Amount that Ike had less than Don
= 4 x 50
= $200
(c)
Value of $100-notes that Don had left
= 10 x 100
= $1000
Total value that Rey had
= 1000 + 3900
= $4900
Number of $100-notes that Rey had
= 4900 ÷ 100
= 49
Answer(s): (a) Ike; (b) $200; (c) 49
