Adam has some $5-notes and some $10-notes that add up to $640.
There are 5 more $5-notes than $10-notes.
- What is the value of the extra 5 $5-notes?
- What is the value of one $5-note and one $10-note?
- How many $10 notes are there?
- How many $5 notes are there?
(a)
Value of the extra 5 $5 notes
= 5 x 5
= $25
(b)
Value of one $5-note and one $10-note
= 5 + 10
= $15
(c)
Number of $10 notes
= (640 - 25) ÷ 15
= 615 ÷ 15
= 41
(d)
Number of $5 notes
= 41 + 5
= 46
Answer(s): (a) $25; (b) $15; (c) 41; (d) 46
