Answer 1

Answer:

Options A and C

Solution:

• The two situations that illustrate that the sum of opposite numbers are:
• #1. Shelley finds $50 in an old purse and deposits it in her bank account.
• So she found $50 and deposited $50.
• 50+(-50)=0
• #2. After 3 forward flips and 3 backward flips, Anna is back where she started.
• 3 flips forward: 3
• 3 flips backward: -3
• 3+(-3)=3-3=0
