Priya has a recipe for banana bread. She uses \( 7 \frac{1}{2} \) cups of flour to make 3 loaves of banana bread. Andre will follow the same recipe. He will make \( b \) loaves of banana bread using \( f \) cups of flour. Which of these equations represents the relationship between \( b \) and \( f \) ?
