During Raul’s exercise program, he recorded how much weight he lost or gained each week. After 5 weeks, Raul had collected the data shown in the chart. He
thought, “I can use the Inverse Property and the Identity Property to help me find out how much my weight has changed.”


Week l Weight lost or gained (In pounds)
---------l-------------------------------------------
1 l -3
2 l -2 1/2
3 l +1
4 l -1 1/2
5 l+1

Why is Raul’s reasoning incorrect?
A. The total of Raul’s numbers is not 0.
B. Raul’s list of numbers does not include 0.
C. Raul’s list of numbers includes opposites.
D. Raul cannot add any of the numbers in his list to get 0.
