For the sentence mentioned below, which verb form (singular or plural) of "cost" fits correctly into the blank space and what is your reason for it:
"Every pale tomato slice, wilted pickle, and brown lettuce leaf [cost/costs] an extra 25 cents at Bernie's Burger Emporium."
I'm aware that "every" would take a singular verb in every case. However, does this still hold true when multiple entities are connected by the coordinating conjunction "and"?
Would your answer change if I write something like this:
"Every item 1, every item 2, and every item 3 [cost/costs] an extra . . ."
