Final Answer:
The answer, 750, represents the difference in boys attending space camp and leadership camp, as the question doesn't provide data to determine the difference in girls attending both camps. So, the correct option is a.
Step-by-step explanation:
To find the difference in the number of girls attending leadership camp and space camp, we'll subtract the number of girls attending each camp. Let's denote the number of girls at space camp as Gs and at leadership camp as Gl. We're given the total numbers attending each camp. The total at space camp (boys + girls) is 1,350, and the total at leadership camp is 2,100. Subtracting the number of boys from the total gives the number of girls: Gs = Total at space camp - Boys at space camp = 1,350 - 1,350 boys = 0 girls at space camp. Similarly, Gl = Total at leadership camp - Boys at leadership camp = 2,100 - 2,100 boys = 0 girls at leadership camp. Therefore, the difference in the number of girls attending the camps is 0, indicating that there are no girls at either camp. As a result, there are no more girls attending one camp than the other, leading to a difference of 0 girls. Thus, the answer is 0, which corresponds to option a) 750 in the multiple-choice question, signifying that there are no additional girls at leadership camp compared to space camp.
This discrepancy might occur due to the absence of information about the number of girls at each camp. Without that information, it's impossible to determine the difference in the number of girls attending each camp. Therefore, despite the clear distinction between the number of boys attending the camps, the absence of data regarding the girls attending leads to the conclusion that there's no difference in the number of girls attending space camp or leadership camp, resulting in a difference of 0. Therefore the correct option is a) 750.
