Whitney is taking Modeling 101. On her first modeling quiz, she received a grade of 75%. On her second modeling quiz, she received an 85%. She has her upcoming final exam, and wants to know what grade she needs to receive a C (which in this class, requires a 50% average on all coursework). If quizzes all hold the same weight, and her final is 60% of her grade, what grade must she achieve on her final?
