Ty, Tom and Joe had the same number of notes. Ty and Tom had a mix of $100-notes and $10-notes. Tom had 10 $100-notes while Ty had 13 $100-notes. Joe only had $100-notes.

1. Who had the least amount of money?
2. How much less did Tom have than Ty?
3. Ty used all his $10-notes to buy a wallet. He then had $3300 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 Tom had the least number of $100-notes, he had the least money.

(b)
Number of less $100-notes that Tom had than Ty
= 13 - 10
= 3

Difference in the value of $100-note and $10-note
= 100 - 10
= $90

Amount that Tom had less than Ty
= 3 x 90
= $270

(c)
Value of $100-notes that Ty had left
= 13 x 100
= $1300

Total value that Joe had
= 1300 + 3300
= $4600

Number of $100-notes that Joe had
= 4600 ÷ 100
= 46

Answer(s): (a) Tom; (b) $270; (c) 46
