I just want my answer checked!

Jacob is on a new exercise regimen. To begin, his trainer does not want him to complete more than a total of 22 lunges and sit-ups. For every lunge that he completes, Jacob burns 30 calories. He burns an additional 20 calories for every sit-up. His goal is to burn at least 440 calories during a workout session. Which is a combination of lunges and sit-ups that Jacob can complete in a session?

4 lunges and 19 sit-ups
5 lunges and 13 sit-ups
5 lunges and 16 sit-ups
6 lunges and 12 sit-ups

The answer would be 6 lunges and 12 sit-ups right?
