Answer:
Least cost per kilogram is "$5 for 2.0 kg"
Step-by-step explanation:
To get cost per kilogram, we divide the cost given by the kg given.
1. We need to divide 4 by 1.5 to get cost per kilogram.
Cost/Kg = [tex]\frac{4}{1.5}=2.67[/tex]
2. We need to divide 5 by 2.0 to get cost per kilogram.
Cost/Kg = [tex]\frac{5}{2.0}=2.5[/tex]
3. We need to divide 7 by 2.5 to get cost per kilogram.
Cost/Kg = [tex]\frac{7}{2.5}=2.8[/tex]
4. We need to divide 8 by 2.5 to get cost per kilogram.
Cost/Kg = [tex]\frac{8}{2.5}=3.2[/tex]
As we can see, the second option costs the least per kilogram.
