Answer:

  • 25

Step-by-step explanation:

Given

  • Total number of participants= 80
  • Male = x
  • Female = 80 - x
  • Average = 58.5
  • Average for male = 64
  • Average for female = 56

Equation to reflect the sum:

  • 64x + 56(80 - x) = 80*58.5
  • 64x - 56x = 80*(68.5 - 56)
  • 8x = 80*2.5
  • x = 25

The answer is 25 male participants
