<human>:  Martin went to a store to buy a new television set. He decided to spend no more than $1,000 and the sales clerk offered him the TV for $100 less and an additional 20% off. How much lower was the price of the television than the amount Martin decided to spend?
<bot>: How much did the seller offer him the TV for? ** The seller has offered him the TV for 1000 - 100 = $<<1000-100=900>>900.
How much was the discount on the television? ** The discount on the television was 900 * 20/100 = $<<900*20/100=180>>180.
What was the final price of the television? ** The final price of the television is therefore 900 - 180 = $<<900-180=720>>720.
How much did Martin save? ** Martin was able to save 1000 - 720 = $<<1000-720=280>>280.
