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? Give me reasons, before answering the question
His order came out to 7 * 200 = $1400. So there was 1400 - 1000 = $400 that qualified for the discount. So his discount saved 400 * .1 = $40. So his purchase came out to 1400 - 40 = $1360. So the final answer is 1360.
