Final answer:
John's dog initially weighed 7 pounds, and after tripling its weight each year for two years, it weighs 63 pounds. This is equivalent to 1008 ounces.
Step-by-step explanation:
The question is about calculating the weight of John's dog after it has tripled in weight each year for two years, starting from an initial weight of 7 pounds. To solve this, we'll first determine the weight after the first year, and then the weight after the second year.
- Initial weight: 7 pounds
- Weight after first year: 7 pounds × 3 = 21 pounds
- Weight after second year: 21 pounds × 3 = 63 pounds
Now, we need to convert pounds to ounces, knowing there are 16 ounces in a pound.
63 pounds × 16 ounces/pound = 1008 ounces
