Would it make sense to describe the total weight of Mark's dinner in tons? Why or why not?​
tatyana61 [14]

Answer: No

Step-by-step explanation:

It would not make sense to describe the total weight of Mark's dinner in tons. A ton is equivalent to 2000 pounds, which is 600 pounds heavier than what was considered the world's heaviest man. Depending on the context of the problem, I doubt Mark is eating such large amounts of food.
