Dwayne wants to attend more group exercise classes at his gym. This week, he plans to attend 4 cardio classes and 5 weightlifting classes, which will last a total of 377 minutes. Next week, he hopes to attend 4 cardio classes and 3 weightlifting classes, which will last a total of 303 minutes. Given that all cardio classes and all weightlifting classes are the same length, how long is each class?

Answer: 37 minutes long

Explanation:

let y = the amount of weightlifting classes

5 - 3 = 2

2 weightlifting classes = 377 - 303

2y = 74

y = 37

each weightlifting class is 37

so each class is 37 minutes long
