Question

The yearbook committee is distributing yearbook to students by class. Each class has approximately the same number of students. The table shows # of volunteers who helped distribute books to each of four classes and time needed to distribute books. Which function models data?

Table:
# of volunteers(n):2,5,8,11
Time in min(t):220,88,55,40

A. nt=80
B. nt=180
C. nt=222
D. nt=440

Answer 1

n=2 corresponds with t=220 (you might think of it as an ordered pair (n,t)=(2,220)). All the models are set up in the form nt= something. So, just check what it is. In this case, nt=2(220)=440. You can confirm by checking another pair.
