In 1854, during the California gold rush, each ounce of gold was worth $20, and the largest known mass of gold found in California was worth $62,400 in that year. What was the weight, in pounds, of this mass of gold?
Correct answer: C. 195
- A. 188
- B. 190
- C. 195
- D. 198
Explanation
The correct answer is 195. Since the mass of gold was worth $62,400 and each ounce of gold was worth $20, the mass of the gold was 62,400 / 20 = 3120 ounces. Since 1 pound = 16 ounces, 3120 ounces is equivalent to 3120 / 16 = 195 pounds.
