Adam has some $5-notes and some $10-notes that add up to $780.
There are 3 more $5-notes than $10-notes.
- What is the value of the extra 3 $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 3 $5 notes
= 3 x 5
= $15
(b)
Value of one $5-note and one $10-note
= 5 + 10
= $15
(c)
Number of $10 notes
= (780 - 15) ÷ 15
= 765 ÷ 15
= 51
(d)
Number of $5 notes
= 51 + 3
= 54
Answer(s): (a) $15; (b) $15; (c) 51; (d) 54
