Adam has some $10-notes and some $50-notes that add up to $160.
There are 4 less $50-notes than $10-notes.
- What is the value of the extra 4 $10-notes?
- What is the value of one $10-note and one $50-note?
- How many $50 notes are there?
- How many $10 notes are there?
(a)
Value of the extra 4 $10 notes
= 4 x 10
= $40
(b)
Value of one $10-note and one $50-note
= 10 + 50
= $60
(c)
Number of $50 notes
= (160 - 40) ÷ 60
= 120 ÷ 60
= 2
(d)
Number of $10 notes
= 2 + 4
= 6
Answer(s): (a) $40; (b) $60; (c) 2; (d) 6
