Answer:
The total surplus will be maximized if Jason installs the muffler and the neighbors do not install soundproofing.
Step-by-step explanation:
First, according to the relationship, L > E > C, since the loss is greater than the cost of either installing a muffler or installing a soundproofing, one of the muffler or the soundproofing must be installed to avert the loss.
Moreover, since it is cheaper to install a muffler than to install a soundproofing, it is more economical to install a muffler provided both serve the same purpose of stopping the loud noise.
