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

### Instruction:
John receives $100 from his uncle and gives his sister Jenna 1/4 of that money. He goes and buys groceries worth $40. How much money does John have remaining?

### Response:
When John gives his sister 1/4 of his money, he parts with 1/4*100 = <<1/4*100=25>>25 dollars
He still has 100-25 = <<100-25=75>>75 dollars
After buying groceries worth $40, he is left with 75-40 = <<75-40=35>>35 dollars.
