Answer:
Least cost per kilogram is "$5 for 2.0 kg"
Step-by-step explanation:

Cost/Kg = 
2. We need to divide 5 by 2.0 to get cost per kilogram.
Cost/Kg = 
3. We need to divide 7 by 2.5 to get cost per kilogram.
Cost/Kg = 
4. We need to divide 8 by 2.5 to get cost per kilogram.
Cost/Kg = 
As we can see, the second option costs the least per kilogram.
