25 out of 100 percent of her time = 1 hour

A) every 50 students is 1 representative, so:
r = (a+b+c+d+e)/50
b) (1587 + 985 + 2052 + 824 + 752)/50 = 6200/50 = 124 representatives.
Our answer makes sense since for every representative, there are 50 students. And 50*124 = 6200 total students.
Answer:
