Answer:
You can use a ratio to solve this problem. Use x as a variable for the cups of food in 28 days.
1 (day): 3 (cups)
28 (days): x (cups)
Cross multiply.
x=28(3)
x=84
So, Li’s dog eats 84 cups of food in 28 days.

hope this helped!!
Pythagorean theorem : a^2 + b^2 = c^2
using 3,4,5
3^2 + 4^2 = 5^2
9 + 16 = 25
25 = 25 (correct)
using 8,15,17
8^2 + 15^2 = 17^2
64 + 225 = 289
289 = 289 (correct)
they are Pythagorean triplets because they satisfy the Pythagorean theorem
