How do u know charmed life caitlin's lucky charm is fiction?

I don't know that book, but you know something is fiction when it's something that simply can not happen in real life, also if it's based on a character, like Sammy took a bath when he finished playing soccer, unlike dolphins are mammals, which is nonfiction. Hope this helps! Please rate brainiest answer!

You'll know if something in the book can't possibly happen in real life

total cost of goods sold = $78,520

Explanation:

Inventory Purchases Sales

May 1 1,300 units at $36

May 10 650 units at $38

May 12 910 units

Cost of goods sold = (650 x $38) + (260 x $36) = $34,060

May 20 585 units at $40

May 14 780 units

Cost of goods sold = (585 x $40) + (195 x $36) = $30,420

May 31 390 units

Cost of goods sold = 390 x $36 = $14,040

total cost of goods sold = $34,060 + $30,420 + $14,040 = $78,520
