The question is "What's Stella's opportunity cost of working on her serve for an hour?" The rest of the info looks like it's meant to confuse you. They charge $10 an hour. She values an hour of her time at $20. I believe that means she would pay $20. Hope this helps!

Get these by adding/subtracting the number at the end (use the opposite operation) and then divide the coefficient from both sides.
