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!
29 - 29 x 15= 24.65
24.65 + 24.65 x .07= 26.3755 which rounds to 26.38
The answer is $26.38
