Adam has some $5-notes and some $20-notes that add up to $310.
There are 2 less $20-notes than $5-notes.
- What is the value of the extra 2 $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 2 $5 notes
= 2 x 5
= $10
(b)
Value of one $5-note and one $20-note
= 5 + 20
= $25
(c)
Number of $20 notes
= (310 - 10) ÷ 25
= 300 ÷ 25
= 12
(d)
Number of $5 notes
= 12 + 2
= 14
Answer(s): (a) $10; (b) $25; (c) 12; (d) 14
