To determine the order of items from the least price per gram to the greatest price per gram, we need to compare the given prices for each item. The prices per gram are:
- Item A: \[tex]$0.06 per gram
- Item B: \$[/tex]0.054 per gram
- Item C: \[tex]$0.30 per gram
Now, let's compare these prices:
1. Item B costs \$[/tex]0.054 per gram, which is the lowest price among the items.
2. Item A costs \[tex]$0.06 per gram, which is the next higher price than Item B.
3. Item C costs \$[/tex]0.30 per gram, which is the highest price among the items.
Therefore, the correct order from the least price per gram to the greatest price per gram is:
[tex]\[ \text{B, A, C} \][/tex]
The correct answer is:
[tex]\[ \boxed{B, A, C} \][/tex]
