Reasoning and answer: Felix's brother weighs 200 pounds because 600 / 3 = 200. Felix weighs 100 pounds because 200 / 2 = 100. Felix can lift 150 pounds because 100 x 1.5 = 150.
The answer: 150

Reasoning and answer: Let's use r for the cost of each necklace. 4 * 12 + 8 * r = 80. 48 + 8 * r = 80. 8 * r = 80 - 48 = 32. 8r = 32. r = 4 dollars for each ring.
The answer: 4
