Ben, Ike and Tim had the same number of notes. Ben and Ike had a mix of $100-notes and $50-notes. Ike had 13 $100-notes while Ben had 18 $100-notes. Tim only had $100-notes.
- Who had the least amount of money?
- How much less did Ike have than Ben?
- Ben used all his $50-notes to buy a wallet. He then had $3100 less than Tim. How many $100-notes did Tim 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 Ben
= 18 - 13
= 5
Difference in the value of $100-note and $50-note
= 100 - 50
= $50
Amount that Ike had less than Ben
= 5 x 50
= $250
(c)
Value of $100-notes that Ben had left
= 18 x 100
= $1800
Total value that Tim had
= 1800 + 3100
= $4900
Number of $100-notes that Tim had
= 4900 ÷ 100
= 49
Answer(s): (a) Ike; (b) $250; (c) 49
