Option 2: 
1/2 fraction of whole carton was used for each serving
Answer:
Step-by-step explanation:
y/3-5=3
add 5 to both sides
y/3=8
multiply both sides by 3
y=8 x 3
y=24
Distribute the 2 on the left to get 2e + 8 = 8e - 20
Add 20 to both sides and subtract 2e from both sides.
28 = 6e
Divide both sides by 6.
e = 14/3
The answer would be 8 dogs.
