Answer:

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
