Kayla began a science experiment with 18 grams of an unknown solid. During the experiment, the change in the mass of the solid was -7 grams. What was the mass of the solid at the end of the experiment?

A) Yes, Edna is correct.
B) No. The answer should have been -25 grams, not 25 grams, because the mass of the solid decreased.

C) No. Edna should have added 18 + -17 because she needed to add the initial mass and the change in mass.
