Question

Each Friday, the school prints 400 copies of the school newsletter. The equation c = 400w models the relationshipbetween the number of weeks and the total number of copies of the newsletters printed. What is true of the graph ofthis scenario?A viable point on the graph isThe values of w must be

Answer 1

$c=400w$

Since:

$\begin{gathered} (w,c)=(8,3200) \\ 3200=400(8) \\ 3200=3200 \\ True \end{gathered}$

(8,3200) is a viable point

---------------------------

Since w is the number of copies of the school newsletter, the values of w must be whole numbers
