Answer:
[tex]60\text{ students}[/tex]
Explanation:
Here, we want to get the total number of players in the league
From the question, 30% can spike the ball with their left hand
Let the number of students in the league be S
30% of this number is 18
Mathematically:
[tex]\begin{gathered} \frac{30}{100}\times S\text{ = 18} \\ 30S\text{ = 18}\times100 \\ S\text{ = }\frac{18\times100}{30} \\ S\text{ = 60} \end{gathered}[/tex]
