Adam has some $10-notes and some $50-notes that add up to $650.
There are 5 less $50-notes than $10-notes.
- What is the value of the extra 5 $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 5 $10 notes
= 5 x 10
= $50
(b)
Value of one $10-note and one $50-note
= 10 + 50
= $60
(c)
Number of $50 notes
= (650 - 50) ÷ 60
= 600 ÷ 60
= 10
(d)
Number of $10 notes
= 10 + 5
= 15
Answer(s): (a) $50; (b) $60; (c) 10; (d) 15
