Ken, Don and Kit had the same number of notes. Ken and Don had a mix of $50-notes and $20-notes. Don had 14 $50-notes while Ken had 19 $50-notes. Kit only had $50-notes.
- Who had the least amount of money?
- How much less did Don have than Ken?
- Ken used all his $20-notes to buy a wallet. He then had $950 less than Kit. How many $50-notes did Kit have?
(a)
The three boys had the same number of notes.
$50-notes have a higher denomination than $20-notes.
Since Don had the least number of $50-notes, he had the least money.
(b)
Number of less $50-notes that Don had than Ken
= 19 - 14
= 5
Difference in the value of $50-note and $20-note
= 50 - 20
= $30
Amount that Don had less than Ken
= 5 x 30
= $150
(c)
Value of $50-notes that Ken had left
= 19 x 50
= $950
Total value that Kit had
= 950 + 950
= $1900
Number of $50-notes that Kit had
= 1900 ÷ 50
= 38
Answer(s): (a) Don; (b) $150; (c) 38
