Answer 3

Well first we can eliminate some choices. We know she wants to burn at LEAST 300 so our answer will be greater or equal to 300. We also know that if she's going to be doing both exercises then she'd be COMBINING them to get her fitness goal, only one answer displays that.

Answer 4

A?

Answer 5
