While tablets are expensive, most buyers can save money in the long run by purchasing e-textbooks instead of print books.
However, the amount of money districts spend on paper used for copies, which tablets would largely replace, balances the implementation cost.
The counterclaim goes against the claim by stating that using tablets is not cost effective for replacing textbooks. The rebuttal needs to address this issue of cost and show how the cost is either worth it, or not actually as much as the opponents think. The first option which talks about the 60-dollar difference only furthers the counterclaim; it does not provide a rebuttal. The second option about purchasing e-textbooks shows how the tablets can actually save money "in the long run". This rebuts the counterclaim by showing that the cost is not as high as one might think long term. The third option is simply inappropriate. The tone is too informal and it doesn't provide any facts. It just sounds like a whiny teenager. The last option shows how the tablets will save money in other areas, thus balancing the cost and making it cost effective in the long run.
