Ms. Sites bought candy for the school's Valentine's Candy Grams fundraiser. She bought 8 bags of candy from Costco and had 45 pieces leftover from her SOAR store. If she has a total of 645 pieces, which equation could be used to determine how many pieces of candy were in each bag?

• 45x + 8 = 645

• 8x - 45 = 645
• 645 - 8x = 45

• 8x + 45 = 645
