John used to buy 4 coffees a day for $2 each.  They raised the price by 50% so he cut the number of coffees he drinks in half.  How much money does he save per day compared to what he used to spend?
How many coffees does John buy now? ** He now buys 4/2=<<4/2=2>>2 coffees
How much more does John pay now? ** The new price is 2*.5=$<<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
