Answer:
Step-by-step explanation:
<u>Given</u>
- Total number of participants= 80
- Male = x
- Female = 80 - x
- Average = 58.5
- Average for male = 64
- Average for female = 56
<u>Equation to reflect the sum:</u>
- 64x + 56(80 - x) = 80*58.5
- 64x - 56x = 80*(68.5 - 56)
- 8x = 80*2.5
- x = 25
<u>The answer is </u>25 male participants
