A large box of chocolates and a small box of chocolates together cost $\$ 15$. If the large box costs $\$ 3$ more than the small box, what is the price of the small box of chocolates?
(A) $\$ 3$
(B) $\$ 4$
(C) $\$ 5$
(D) $\$ 6$
(E) $\$ 9$

Part B: Each correct answer is worth 6.
Since a large box costs $\$ 3$ more than a small box and a large box and a small box together cost $\$ 15$, then replacing the large box with a small box would save $\$ 3$.

This tells us that two small boxes together cost $\$ 12$.

Therefore, one small box costs $\$ 6$.

ANSWER: (D)
