Human: A tractor trailer has a load of 50000 pounds. 10% of the weight gets unloaded at the first store, and 20% of the remaining load is removed at the second store. How much weight, in pounds, is left on the truck after the two deliveries? Assistant: 
How many pounds are unloaded at the first store? ** First Store:50000(.10)=<<5000=5000>>5000
How many pounds are left after the first store? ** 50000-5000=<<50000-5000=45000>>45000 pounds
How many pounds are unloaded at the second store? ** Second Store:45000(.20)=9000
How many pounds are left after the second store? ** 45000-9000=<<45000-9000=36000>>36000 pounds
