Adam has some $5-notes and some $20-notes that add up to $470.
There are 4 more $5-notes than $20-notes.
- What is the value of the extra 4 $5-notes?
- What is the value of one $5-note and one $20-note?
- How many $20 notes are there?
- How many $5 notes are there?
(a)
Value of the extra 4 $5 notes
= 4 x 5
= $20
(b)
Value of one $5-note and one $20-note
= 5 + 20
= $25
(c)
Number of $20 notes
= (470 - 20) ÷ 25
= 450 ÷ 25
= 18
(d)
Number of $5 notes
= 18 + 4
= 22
Answer(s): (a) $20; (b) $25; (c) 18; (d) 22
