Unit 1 Summative 1 Study Guide

On Monday, Hailey spends $28. After babysitting she is paid $28. What conclusion can you draw?

• The amounts cannot be compared since the amount of money she had to start is unknown.

• She has the same amount of money she had to start because 28 + (-28) = 0.

• She has more money that she had to start because 28 + 28 = 56.

• She has less money than she had to start because -28 + (-28) = -56.
