A store gives a 10% discount for the amount of the sell that was over $1000.  John buys 7 items that each cost $200.  What does his order cost after the discount?
His order came out to 7*200=$<<7*200=1400>>1400
So there was 1400-1000=$<<1400-1000=400>>400 that qualified for the discount
So his discount saved 400*.1=$<<400*.1=40>>40
So his purchase came out to 1400-40=$<<1400-40=1360>>1360
#### 1360
