The answer to your question is 0.
Here are 3 equivalent expressions that would represent the total number of pencils and pens in Karen's backpack.
1. 4p + 6
2. p+ p + p + p + 6
3. 6 + 4(p)
Each of these has four groups of p +6 represented.
So you just want to find out how many groups of 5 1/2 are in 15 dollars, or just dividing.
15/5.5 = 2.72 dollars
I think you said round to the nearest tenth, so 2.70 dollars.
If 2 bottles=6 and 8 bottles=24 then split 2 bottles and 6 dollars in half
1 bottle=3 dollars
24+3=27
So, $27 for 9 bottles of vinegar.
