Greta bought three bags of candy. Each bag contained 70 pieces of candy. She used 150 pieces of the candy for gift bags. Which diagram shows a way to find n, the number of pieces of candy which were left over?

Responses

Diagram 1:

Total pieces of candy = 3 bags x 70 pieces per bag = 210 pieces
Used for gift bags = 150 pieces

To find the number of pieces left over:
210 - 150 = n

Diagram 2:

Total pieces of candy = 210 pieces
Used for gift bags = 150 pieces

To find the number of pieces left over:
210 - 150 = n

Both diagrams illustrate a way to find n, the number of pieces of candy left over after Greta used 150 pieces for gift bags.
