2012 AMC 8 Problems/Problem 1

Rachelle uses 3 pounds of meat to make 8 hamburgers for her family. How many pounds of meat does she need to make 24 hamburgers for a neighborhood picnic?

$\textbf{(A)}\hspace{.05in}6 \qquad \textbf{(B)}\hspace{.05in}6\dfrac23 \qquad \textbf{(C)}\hspace{.05in}7\dfrac12 \qquad \textbf{(D)}\hspace{.05in}8 \qquad \textbf{(E)}\hspace{.05in}9$

Solution

Since Rachelle uses 3 pounds of meat to make 8 hamburgers, she uses $\frac{3}{8}$ pounds of meat to make one hamburger. To find out the pounds of meat she needs for 24 hamburgers, multiply $\frac{3}{8}$ and 24 to obtain the answer, $\boxed{\textbf{(E)}\ 9}$ .
