Plug In. Make m = 2 and n = 3. For Quantity A, the weight of 2 peanuts at 3 + 3 mg each is 2 × 6 = 12 mg. For Quantity B, the weight of 3 almonds at 2 + 3 mg each is 3 × 5 = 15 mg. Eliminate (A) and (C). Plug In again to see if you can get a different result. Keep m = 2, and change n to 2. For Quantity A, the weight of two peanuts at 2 + 3 mg each is 2 × 5 = 10 mg. For Quantity B, the weight of two almonds at 2 + 3 mg each is 2 × 5 = 10 mg. Eliminate (B), and choose (D).
