Lon, Jon and Joe had the same number of notes. Lon and Jon had a mix of $100-notes and $10-notes. Lon had 7 $100-notes while Jon had 10 $100-notes. Joe only had $100-notes.
- Who had the least amount of money?
- How much more did Jon have than Lon?
- Jon used all his $10-notes to buy a wallet. He then had $2700 less than Joe. How many $100-notes did Joe have?
(a)
The three boys had the same number of notes.
$100-notes have a higher denomination than $10-notes.
Since Lon had the least number of $100-notes, he had the least money.
(b)
Number of more $100-notes that Jon had than Lon
= 10 - 7
= 3
Difference in the value of $100-note and $10-note
= 100 - 10
= $90
Amount that Jon had more than Lon
= 3 x 90
= $270
(c)
Value of $100-notes that Jon had left
= 10 x 100
= $1000
Total value that Joe had
= 1000 + 2700
= $3700
Number of $100-notes that Joe had
= 3700 ÷ 100
= 37
Answer(s): (a) Lon; (b) $270; (c) 37
