A store decides to shut down and sell all of its inventory. They have 2000 different items which would normally retail for $50. They are offering an 80% discount and manage to sell 90% of the items. They owed $15000 to their creditors. How much money do they have left after the sale? Give me reasons, before answering the question
They sold 2000 * .9 = 1800 items. They offered a 50 * .8 = $40 discount. That means that each item sold for 50 - 40 = $10. So they made 1800 * 10 = $18,000. So they had 18,000 - 15,000 = $3,000 leftover. So the final answer is 3000.
