<em>The most effective claim for Brooke presentation will be " if 75% of the 7th grade runs, we will earn money for gym equipment."</em>
Brooke has to persuade students to participate in the annual 7th grade Fun Run. Brooke needs a strong and attractive argument to convince them. She needs to find something that can catch the 7th graders attention in order to participate in the event. That is why if she shares the argument of a benefit for them, the probability of participation would increase. So the most effective claim for Brooke presentation will be " if 75% of the 7th grade runs, we will earn money for gym equipment."
