Question: A factory produces 90 refrigerators per hour. It also produces 70 more coolers than refrigerators per hour. How many products did the factory produce for 5 days if it works 9 hours a day? Think carefully first, then make a decision:
The factory produces 90 + 70 = 160 coolers per hour. The factory works 5 * 9 = 45 hours in 5 days. The factory produces ( 90 + 160) * 45 = 11250 products for 5 days. So the answer is 11250.
