Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
Joan has 2 hours to get all her music practice done. She spends 30 minutes on the piano, 25 minutes writing music on her computer, and 38 minutes reading about the history of the piano. Her final work is to use a special finger exerciser. How much time does she have left to use this?

### Response:
She has 60 * 2 = <<60*2=120>>120 minutes to practice.
She has already spent 30 + 25 + 38 = <<30+25+38=93>>93 minutes on her work.
She has 120 - 93 = <<120-93=27>>27 minutes to use on finger exercise.
