Katena32 [7]

Answer:

  • 225 notes

Step-by-step explanation:

Let the number of notes is x.

<u>20% of notes is: </u>

  • 0.2x

<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>

  • x - 0.2x - 0.32x =
  • 0.48x

<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
