Together, they stocked 60 cereal boxes on the display. Kay stocked 8 more than of the boxes that Terri stocked. Which system of equations can be used to determine the number of cereal boxes Terri stocked and the number of cereal boxes Kay stocked for the store display?

x + (x+8) = 60

Therefore Terri stocked 26 boxes and Kay stocked 26+8 boxes = 34 boxes

Explanation:

Let the boxes stocked by Terri = x

Therefore the boxes stocked by Kay = x + 8 because he stocked 8 more boxes

Hence since they both stocked 60 boxes

x+x+8 = 60

2x = 60 - 8

2x = 52

divide both sides by 2

x = 26

Therefore Terri stocked 26 boxes and Kay stocked 26+8 boxes = 34 boxes
