To do this, we must set up ratios:
Option One:
The first options costs only $0.0092/gram (a fraction of a penny)!
Option Two:
The second option costs only $0.0085/gram (cheaper than option one)!
Option Three:
This requires a little more work. First, we have to convert the grams into kilograms. For every 1 kg, there is 1,000 g. Therefore, 1,000g costs $5.65. Next, we set up the ratio as usual:
The third option costs $0.00565/gram.
Therefore, option three is the cheapest!
Hope this helps!
