$50 |
$100 |
Number |
3 u |
2 u |
Total value |
50 x 3 u = 150 u |
100 x 2 u = 200 u |
(a)
Change ratio into units.
Number of $50 notes = 3 u
Number of $100 notes = 2 u
Total number of notes
= 3 u + 2 u
= 5 u
(b)
Difference in the number of notes
= 3 u - 2 u
= 1 u
(c)
Total value of $50 notes
= 3 u x 50
= 150 u
Total value of $100 notes
= 2 u x 100
= 200 u
Total value of notes
= 150 u + 200 u
= 350 u
(d)
Difference in the value of notes
= 200 u - 150 u
= 50 u
Answer(s): (a) 5; (b) 1; (c) 350; (d) 50
