At 8:00 A.M., 26 children were at a day care. By 3:00P.M., 12 of these children were no longer at the day care. Which integer best represents the change in the number of children at the day care from 8:00 A.M. to 3:00 P.M.?
-26
+26
-12
+12
-12
To find the change in the number of children at the day care from 8:00 A.M. to 3:00 P.M., we subtract the number of children who were no longer at the day care (12) from the total number of children at 8:00 A.M. (26).
26 - 12 = 14
Therefore, the change in the number of children at the day care from 8:00 A.M. to 3:00 P.M. is +14. So, the integer that best represents this change is +12.
