Answer:
68
Step-by-step explanation:
First you multiply 8 and 4 to get 32 and that shows you how many campers have agreed to help. Next you have to subtract 32 from 100 to know how many more people you need.
The correct answer is number one
2th bounce- 80
5th Bounce- (-)200
9th Bounce- (-)560
Every time the ball bounces it loses 40cm because on the first bounce 160cm-120cm=40cm
And the score goes down by 40 every time and since we go into the negatives the negatives sometimes add on top of each other
