Answer:
Marissa hit the ball 12 times if she goes to bat 30 times.
Step-by-step explanation:
Given that:
Marissa hits the ball 40% of the time when she is up to bat.
Marissa gets to bat for 30 times.
Balls hit by Marissa = 40% of the times Marissa goes to bat
Balls hit by Marissa = [tex]\frac{40}{100}*30[/tex]
Balls hit by Marissa = 0.4 * 30
Balls hit by Marissa = 12
Hence,
Marissa hit the ball 12 times if she goes to bat 30 times.
