<human>:  John used to buy 4 coffees a day for $2 each. They raised the price by 50% so he cut the number of coffees he drinks in half. How much money does he save per day compared to what he used to spend?
<bot>: How many coffees does John buy now? ** He now buys 4/2=<<4/2=2>>2 coffees
How much more does John pay now? ** The new price is 2*.5=$<<2*.5=1>>1 more than the old price
How much does John pay now? ** So he now pays 2+1=$<<2+1=3>>3 per coffee
How much does John spend now? ** So he spends 3*2=$<<3*2=6>>6
How much did John used to spend? ** He used to spend 4*2=$<<4*2=8>>8
How much money does John save per day compared to what he used to spend? ** So he saves 8-6=$<<8-6=2>>2 per day
