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

### Instruction:
 John used to buy 4 coffees a day for $2 each. They raised the price by 50% so he cut the number of coffees he drinks in half. How much money does he save per day compared to what he used to spend?


### Response:
 Für 4 Kaffees hat John früher 4 * 2 = <<4*2=8>>8 Dollar pro Tag ausgegeben.
Der Preis für Kaffee beträgt jetzt 2 * 1,5 = <<2*1.5=3>>3 Dollar pro Kaffee.
John kauft 2 Kaffees pro Tag zum neuen Preis. Also gibt er $3 x 2 = $<<3*2=6>>6 pro Tag aus.
John spart $8 - $6 = $<<8-6=2>>2 pro Tag.
