One of the strongest restaurant concepts fast casual restaurants do not offer a full table service; however, they do advertise higher quality food in comparison to fast food restaurants. As a result, fast casual restaurants are perceived as an intermediate option between fast food and casual dining, and usually priced accordingly. Fast casual is now the fastest growing category in the food serviceindustry.

D.Company B’s costs would increase by .5 multiplied by the average cost of the alternative to single-use plastic.解释：
