Answer:
Step-by-step explanation:
Let the number of notes is x.
<u>20% of notes is: </u>
<u>40% of the remainder is: </u>
- 40% of 0.8x, so it is
- 0.8x*0.4 =
- 0.32x
<u>Remaining notes are:</u>
<u>Total of the notes:</u>
- 0.2x*10 + 0.32x*5 + 0.48x*2 = 1026
- 2x + 1.6x + 0.96x = 1026
- 4.56x = 1026
- x = 1026/4.56
- x = 225
