    Time per cardio class: 32 minutes

    Time per weightlifting class: 40 minutes

    Step-by-step explanation:

    Start by creating a system of equations:

    let c = the time per cardio class

    let w = the time per weightlifting class

    4c + 5w = 328

    4c + w = 168

    Solving for c and w get you 32 minutes and 40 minutes respectively
