The first thing that we are going to do in this case is to find the slope of the line for the function that simulates the amount of food of the elephant.
We have then:
m = (y2-y1) / (x2-x1)
Substituting any two points:
m = (625-125) / (5-1)
m = 125 pounds / day
125> 13.5
Answer:
The elephant eats more than the tiger daily.
