d.

Answer 1

Convert everything to pounds (use 1 ton = 2000 lb, 1 kg = 2.20462 lb), add, then convert to ounces (1 lb = 16 oz).

- Sandwich: 0.462 lb
- Sneaker: 290.87 g = 0.29087 kg → 0.29087·2.20462 = 0.6412578 lb
- Pinecone: 0.0000453 ton = 0.0000453·2000 = 0.0906 lb
- Dog collar: 0.246 kg → 0.246·2.20462 = 0.5423365 lb

Total = 0.462 + 0.6412578 + 0.0906 + 0.5423365 = 1.7361943 lb
In ounces: 1.7361943·16 = 27.78 oz

Answer: d. 27.78 oz
