During a science lab experiment, Bailey was instructed to mix two solutions together. Before mixing solution A and solution B, she was to measure and record their temperatures. She measured and recorded the temperature for solution A as LaTeX: 12^o12 oC. She then mixed the two solutions and measured the new temperature at LaTeX: 0^o0 oC. Bailey then realized she forgot to measure the temperature of solution B before she mixed it with solution A. What was the temperature of solution B before the solutions were mixed together?
