(a)
Change ratio into units.
Number of $2 notes = 11 u
Number of $50 notes = 8 u
Total number of notes
= 11 u + 8 u
= 19 u
(b)
Difference in the number of notes
= 11 u - 8 u
= 3 u
(c)
Total value of $2 notes
= 11 u x 2
= 22 u
Total value of $50 notes
= 8 u x 50
= 400 u
Total value of notes
= 22 u + 400 u
= 422 u
(d)
Difference in the value of notes
= 400 u - 22 u
= 378 u
Answer(s): (a) 19; (b) 3; (c) 422; (d) 378
