Letter of recommendation for LMU

My daughter is going to apply for accounting major at Loyola Marymount University for early action. This school is supposed to be her safety school based on her GPA and SAT score. On the school website, it says one letter of recommendation is required and the 2nd one is optional. She’s got one from her Calculus AP teacher. Question - Will the 2nd letter of recommendation benefit her by increasing her chance of acceptance?
