I did not really understand the first question, but I will answer the second.
If Gracie eats 165 pounds of food a day and Maxie eats 308 pounds, they eat 473 pounds a day together.
Since there are 365 days in a year, we multiply 473 with 365. You would get 172,645.
Thus, the two elephants eat 172,645 pounds of food each year.
For the second question on that page, I don’t know how much the gorilla eats.
Please mark brainliest if this helped! :))
