Had to look for the missing options and here is my answer.
Based on the study being conducted by Miranda which was covers students who would attend a students only school dance, the sample that is most likely going to give a representative sample for the poll would be "<span>twenty names from each grade pulled blindly from a container filled with the names of the entire student body </span><span>written on slips of paper." Hope this helps.</span>
divide the original price by 2 since it is half off. that gives you 6.44. so you would multiply 6.44 by 5, since allison wants 5 cases. that gives you 32.20 dollars
